When in Paris next month, I plan to stop into the Bar Hemingway. When the bill comes, I want to neither offend the bartender nor part with many more euros than is necessary.
I am familiar with restaurant tipping etiquette, but what should I do when ordering a cocktail at a fancy bar in Paris? what about when ordering a glass of wine?
Thank you in advance for your advice.
(And I hope it's not too off-topic for me to ask a cocktail-related question on Chowhound - but many of you seem so knowledgeable about Paris, and sometimes a chowhound needs a drink!)
