Funny story. Grocery stores are just as irritating here in France--I see no logic in the way the aisles are arranged (I won't give examples because I will start ranting) you need certain euro pieces to unlock a grocery cart, but I often don't have the right piece, and the cashiers like to chat endlessly to each other while ignoring the long lines of customers. No-one but me seems particularly bothered, c'est la vie, I guess. Complaining to anyone in my fractured French is hardly worth the bother so I'm even more cranky and irritable than I usually am once I get home.
