I work in a city that draws tourists from all over the world. One of the big sightseeing spots is directly below our offices. There are several drummers that set up their drums, buckets and glass bottles below our windows. Even though we are 10 stories up the never ending banging gets on our nerves after an hour, after eight hours we're really over it and tempted to snatch their drumsticks. Of course we never would. I can't leave my desk, but they can find another spot to drum for tips.
I don't think they're rude per se, just clueless. We do have merchant sponsored tour information personnel that roam the area and they will ask them to move after an hour or so. Even the police officers on the beat get tired of it and have them move along.
I have no advice, just this observation and commiseration.
