Not according to four tuxedo-wearing Frenchmen who took to line 5 of the Paris Metro at Place d'Italie last week to eat a raclette, washed down by a few glasses of fine wine.
The men set up a table between the seats, placed a table cloth over it and served up the usual cold meats, potatoes and pickles that make up a raclette dinner. The all-important cheese was melted using small candles rather than the usual electric grills.
If you don't believe it, just watch the video below.
The men told how they got on at the beginning of the line at Place d'Italie to be sure to have seats, something which is never guaranteed as anyone who takes the Metro in Paris will confirm.
The stunt was almost stopped before the wine was even opened when a security guard asked what they were doing and checked that they didn't have any candles.
“Luckily the candles were not lit at this point,” said Thomas.
Could dining on the Paris Metro take off?
Perhaps Paris Metro authorities should think about installing restaurant coaches in Metro trains for commuters to enjoy a sit-down dinner on the way home from work.
Or would RER passengers be tempted by Champagne breakfasts on their way to work?
