An evening with dog haters

A good productive work day, and later Philipp, Djeili and I met our good friends C and A who will too soon move back to the States. 
We had dinner and a good english chat at a restaurant with not very nice people at the table next to us. They hated a dog being in the restaurant and discussed loudly in German that it is unbelievable to take a dog to a restaurant and that we, whatever stupid country we might come from, will not have trained the dog according to the Swiss rules (oh, we've done all requested and more!), and that the dog will for sure attack somebody and this will cost us shitloads and we don't look like we have enough money for that. Well, they were shitfaced people obviously coming from drinking at the carnival. 
We decided to leave. Different reactions from our side - Philipp decided to show them that we have the upper hand and wished them "A nice evening" in German, I decided to make them growl and I wished them a "further grumpy evening" in German. It made their eyes pop. I am sure they spent loads of time afterwards to discuss how nasty all Germans are and that they should be driven out the country together with all the dogs and the asylum seekers and all other foreigners, and everybody else who is not like them.
