we play this one place where we basically set up at the back of a restaurant, with a walkway right past me as i play. there is enough space for 2 ppl to walk by at the same time without touching me as i play. but, our fans gather, put their drinks on my amp, talk to me, put their arms around me, and even pinched my a$s as i played (yes it was a girl, and my wife was in the audience, so no it wasn't cool). i had to stop once to prevent my amp from being shoved off my stack. i have no idea how to deal w/ this without being rude. i mean, our fans get all excited, and i don't want to discourage it - but it was incredibly frustrating.
