Supermarkets could find themselves facing a bill for £68 for every abandoned shopping trolley cleared from the streets of Crawley.
Crawley Borough Council is considering introducing the charges after concerns were raised about the increasing number being dumped in the area.
A report due to go before the council's cabinet later this month stated that, during a survey carried out once a week over a four-week period, 76 trolleys were found, with 14 not picked up for more than a week.
As well as causing traffic hazards, blocking pavements and becoming a focal point for fly-tipping, the report said that abandoned trolleys gave the impression that an area was less attractive and less safe.
Most of the trolleys were dumped in the West Green, Northgate, Broadfield, Langley Green and Southgate neighbourhoods, while none were reported in Forge Wood, Furnace Green, Gossops Green or Three Bridges.
The majority found were from Morrisons.
The proposed charges are: £27 for the collection of the trolley, £15 to store it, a £26 administration fee, and £10 for disposal of the trolley.
The charges will rise for each week the trolley is left unclaimed, culminating in court fees and an extra charge of £60 if the council is forced to recover the debt through legal channels.
The fire is thought to have been started by a deep fat fryer in the Morrisons cafe.
Emma-Lou Montgomery, associate director from Fidelity Personal Investing’s share dealing service has commented on those Morrisons' figures, which has seen its share price slump around 5% this morning. She said:
Morrisons is clearly open to new opportunities and its wholesale business is growing as today’s trading update show. It already delivers via Ocado and supplies corner shops and Amazon. But Amazon ultimately remains the enemy of the sector, not an ally. Pressure is continuing to mount, as we’ve seen, with Sainsbury’s buying up Argos and now Asda in an attempt to beef up its operations. And that’s not forgetting the double-pronged threat from German discounters Aldi and Lidl, which Morrisons is well aware of.
The FTSE 100 is now trading down 0.32% at 7,080.93.
Morrisons continues to lead the fallers and is now down 5.5% at 240.47p after it released a third quarter trading update.
Associated British Foods, which owns Primark, has jumped to the top of the blue chip risers, up 2.76% at £24.55 after it reported full-year figures.
The FTSE 250 is up 0.34% at 19,128.39.
Morrisons is the biggest faller on the FTSE 100 in opening trade after third quarter results showed a slowdown in like for like retail sales growth.
Its share price fell by 4.2% to 243.95p.
Although like-for-like sales for the three months to 4 November grew, it was driven by its wholesale business through which it supplies goods to Amazon and McColl's.
In retail, same store sales grew but at a slower rate of 1.3% compared to previous quarters.
Delving deeper into Morrisons's third quarter results, retail like-for-like sales growth is slowing while revenue from its wholesale operation is up.
The supermarket chain it expected retail same store sales growth to ease "without the impact of the favourable weather and World Cup which benefited the second quarter".
Morrisons is a wholesale supplier to Amazon and McColl's convenience stores.
