Be thankful you don't need to get from Paris to London today (unless you do, then please tell us your story by emailing firstname.lastname@example.org).
Eurostar is today again telling passengers only to travel from Paris to London "if absolutely necessary".
Its services have been hit once more by long queues caused by industrial action by French customs officers.
The officers are working to rule, and only one of the usual six X-ray machines is being operated.
The company, which has apologised, says tickets can be changed free of charge, or affected passengers can claim refunds.
There are delays of up to an hour on Eurostar services between London St Pancras International and Paris Nord/Brussels Midi due to overhead power supply problems near Stratford.
Delays could continue for the rest of the day.
The Ryder Cup golf tournament in Paris helped Eurostar achieve record sales revenues between July and September.
The cross-Channel rail operator said revenues reached £247m in the third quarter of the year, up 17% on the same period last year.
Year-on-year passenger volumes increased by 12% to three million, including a 21% rise in the number of business customers.
Eurostar said the number of passengers from the US grew by 6%, with many people crossing the Atlantic to attend the Ryder Cup in September.
Leisure traffic was boosted by the new service between the UK and the Netherlands, with an additional 130,000 passengers travelling to Amsterdam and Rotterdam by high-speed rail since the route opened in April.
