Sorry if I'm resurrecting a dormant thread; I'm on my phone. But I just heard about this and I had to share.
I actually heard about this second hand; and it happened probably about 6 or 7 years ago. Friends were at a concert of a band we both like. This band doesn't really do requests that often, and if they do it has to be arranged in advance. Once the setlist is set, it's final.
Apparently, some other fans (Nutsos, I'll call them) didn't know that. When intermission came, the band left their instruments on the stage, as usually. Well, Nutsos, it turned out, wanted to request a song. So the wrote their request on a piece of paper, got up on stage, and WEAVED IT BETWEEN THE BASS STRINGS!
Whaaaaaaat?!?!? Can you even believe it?
First of all, you do not touch something that isn't yours, period.
Second of all, what if they'd damaged the bass?? Popped a string or knocked it over? The show would be shot, and the band would be out the money to have it repaired. It's not a cheapo little bass, either, its fairly high end.
Even still, just the nerve! What goes through some people's heads?
And no, the band did not honour the request.
