I'm the grocer in Turn Back Time - The High Street
Well where do you begin to tell a story like this? It's been the most amazing summer of my life travelling back in time for Turn Back Time - The High Street.
First the Victorian era. We had an absolute shock when we first walked into Shepton Mallet market square. I felt really proud to see our name up above the shop which we would be running for the next six weeks.
Going into the shop for the first time really was like walking back in time. All those history stories and lessons you had at school about the good old days, well this was it! There were sacks of goodies like loose biscuits, sugar cones, flour, lentils and so much more.
That's when the service era began. Customers were seated and their every need was taken care of. The era was one of opulence and saw the arrival of packaged foods.
Customers could take away their goods with much more ease or have them delivered.
We had cigarettes that were said to help with winter coughs and asthma and be especially suitable for women and children - amazing claim eh?!
In episode two, we had the bombshell of all the lads of eligible age being called up to go to war. I thought I was too old but I'm afraid it was not to be.
Whereas men of the time would have been conscripted, I left the shop to reflect on World War 1 with the other men in the programme. That left the girls to finally come out of the back room and see the real world.
At first my wife Debbie was really happy at the fact, because she had been stuck out the back since 1870 and it was now 1916! She aged well, don't you think?
But then it dawned on her that she was on her own, just like all those real girls were back in the Great War. Her happiness soon turned to one of 'Oh my golly, what am I going to do without the boys?'
Then the 1930s, the era of... well, I can only say sugar. Sweets everywhere, almost the entire shop was transformed again into a kiddy's (and Gregg Wallace's) dream come true.
Shelf after shelf of sherbet, toffee, sugared mice, midget gems and loads more.
One thing did surprise me though. The five-a-day slogan we hear so much about nowadays was actually around in the 1930s.
The shop shelves were pretty bare and it stayed that way for most of the era, with the exception of our little surprise. You'll have to watch to find out what I got up to!
I was 'sent to war' again - this time we had a day at Bovington Tank Museum to see a little of what those lads actually had to go through.
Very scary. I'd probably have run away if it was for real. Our tanks were just not up to the quality of the German ones. It took 10 of ours to destroy one of theirs.
That aside, we rode in a Sherman tank and it was a great day (although the marching we had to do beforehand was not quite as much fun).
We spent two nights away from the girls but our hosts were under strict orders to make sure we only had the same rations everyone else had.
I lost weight during that era. Even when we arrived at the accommodation for the final night, all we got was soup and sandwiches - and all we'd eaten that day was an egg and bacon roll.
But on a serious note, I take my hat off to all those brave and courageous people during the war. I am glad we didn't have to do it for six years. Five days was bad enough.
At the end we had a VE day party and all the people of Shepton Mallet cooked up a wonderful array of goodies for us all to eat. A fabulous end to a very hard era.
The Swinging Sixties was when the shop started to resemble a modern day supermarket.
Self service counters, tills with conveyer belts and still retaining an element of personal service for those who weren't quite sure about picking things off the shelves for themselves.
It was a bit saddening as I could see it wouldn't be long before we became a fully fledged supermarket.
I always bang on about the fact that they have destroyed the high street as we used to know it. Now all we have is big out of town car parks with huge great shops attached to them. They're always going to be around but it's so important that the high street can exist along side them.
Debbie had to be the perfect housewife and have my slippers ready every night when I returned home from work, cook a lovely meal and make sure that all was well with me.
I must admit it was nice while it lasted!
She also had to prepare a dinner party for all the other traders. Well, I've never seen such horrible recipes. Tomato mousse made out of tinned condensed soup, orange and tomato salad with mint leaves and watercress... the list of atrocities just went on and on.
By the 1970s, all my fears had come true. We had turned into a supermarket. Just plain old boring food on shelves, no more service, no more interaction with customers, just take the money and send them on their way.
Anyway that's enough moaning. Let's look at the more fun things that happened.
My son Harry and I had to dress up as chickens to sell off our stock during the power cuts of the 1970s. That was a laugh - as was the intercom system in the shop. And punk rockers coming in and nicking stuff from the shelves and defacing the goods with anti-establishment slogans.
The grand opening of the record store with a surprise band was really great fun. You'll have to watch to see who it was but what I will say is - save all your kisses for me guys.
I hope you like my little stories - all the best for now.
