Subject: Paris cafe customs
Hi , I read in Patricia Wells' book Food Lover's guide to Paris , regarding Cafe de la Mairie,

... come early in the morning after picking up a croissand or a pain au chocolat from nearby Gerard MUlot (76 Rue de la Seine) to enjoy a frothy cafe creme and the calm of the city as it wrestles from its slumber....

Has any one done this? I was under the impression the patron would kill me! Or is this a custom in Paris I had no clue about?

Any comment. Thank you Graziella in Miami Beach
