Most people know #### about playing guitar and those that do, are usually crap or trying to steal the guitar off u and show u down. Lol i dont know how many times I've played Smoke on the Water just to impress some randoms. Then when i start playing harder stuff like Hendrix they say "Ohh can you play some Green Day or Simple Plan?"
That's the point I play an old Green Day song and then tell them that Simple Plan are #### and play something good they have never heard of.
I've found though that I get motivated to play in front off people when they piss me off. Though I hate ignorant people and wouldnt play for them usually, the more ignorant they act, the more i play. It's kool, since there are heaps of ignorant people around, so when I get my first gig with my band, it will be awesome
