Of course, this is not something adhered to religiously or otherwise, as one can always fall upon someone simply having a bad day. But here in Paris if someone looks bored with their job, especially in a restaurant or popular store (like the FNAC), they’re probably miserable! And therefore, proceed with caution. Like most others, I have had countless unpleasant experiences in cafés and brasseries, but usually can guess beforehand what is about to befall me. The worst was quite recent, where I asked for bread and was told by the wretched waiter that it wasn’t served with the particular dish I ordered. Trop fort.
