One night we went to dinner on a terrace at a restaurant where the food was New Orlean's food. It was charming, until a rat ran through the terrace and under the feet of some people across the isle from us. A bit later a waiter person came by, and I stopped her and told her about the rat. The people across the isle nodded and said, 'yes, yes'.
She said: "Eeewww, how awful." Yes, it was awful, but I was expecting a little more concern, so I suggested she report it to the manager or owner. She said, "I'm the owner, eeeewww." And walked on.
Not the reaction I expected. I've never gone back.
