No, but my friend has a German mother and she's quite bossy. On the whole I think of them as nice people, although they can seem quite serious and don't seem to laugh and joke around as much as we do.
Some people don't understand why when they're on holiday around the Mediterranean, the Germans get up extra early to put the towel over the sun bed so nobody else can have it.
I think of the leather shorts as a cultural thing where people might dress up for special occasions. I wouldn't mind seeing that and join in with the beer drinking lol. I quite like beer, as opposed the larger that many people drink here, although we're starting to have more and more decent local beers lately.
