I assume they were hoping to make you uncomfortable enough that you would relocate...
It looks like it, but it was absolutely surreal. They were the classic 'idiots abroad', or should I say 'buraks abroad' - even down to the fact that one of them left early to prepare the rosół. For the next few days, we were killing ourselves laughing as they sent someone down early in the morning to place towels in the Germanic fashion ;) It was a shame that their towels didn't mysteriously end up in the sea :(
..... or they come to sit right with you on the bus/tram/train or at restaurant/café when the whole place is empty or almost empty
Yes! I've had this on the bus before - an large, mostly empty bus, and I'm fond of sitting at the front of the bus. I'm sitting there peacefully when some middle aged guy gets on with his wife, and he sits right next to me with his wife sitting on the seat across. It was painfully obvious that she wanted to sit where I wanted to sit, but of course, it was better for her to make rude comments than to simply ask nicely if she could have the seat.
