One of the reasons I like London is its full or antique markets. However there is no beating the Paris fleamarket. You can spend days there, as I frequently have. Plenty of restaurants. toilets, shippers, money change agents and anything you could want.
I can recall spending a day there and not coming back until 9 0clock in the evening (met some dealers and went for a meal). One of the idiots in our party had left a bag with all her travel checks, money and passport on the floor under a table and then gone off and left it. When they went to the police to file a report the police spoke no English (or so they claimed) and they had to wait for someone to come and translated for them, which took hours. Too late to go to the British Embassy to apply for an emergency passport. Of course I was made to feel BAD because I had not been with them and none of them spoke French.
Next morning I advised them to get to the British Embassy as early as possible and to spend a lot of time queuing, waiting, answering questions and filling in forms.
"But surely you arn't going to leave us again? We dont speak French."
"Ive got some really good news for you. They speak English at the British Embassy so Im off to the fleamarket again."
Needless to say the atmosphere for the remainder of the stay in Paris was distinctly cool. Fortunately the fleamarket is open all through the weekend.
