(although a lot of American wait staff really push the limit here).
My wife insisted on stopping in a little restaurant near the Louve. We were seated and we ordered. Others came in, the waitress moved us and two other couples.
We had our drinks and waited for our food. Others came in, the waitress moved us and three other couples.
Our food arrived and we began to eat. Others came in, the waitress approached and I said “Non!”
My wife and I once made the mistake in 1995 of sitting down at a cafe near Notre Dame in Paris. They posted their prices on a tiny blackboard in the back that I couldn't read. We ordered two cokes.
The bill at the exchange rate at the time was $24.00.
Like many tourist meccas, Paris has its share of jerks and rip-off artists.
