I promise i'm in a good mood today..just annoyed

I think people try to come into my store and annoy me. There are two way in which they can succeed in doing this. One is letting your kids run a muck and destroy everything in the store, the other is when people try to hum or sing along to the songs that are playing in the store. When my ipod is on, I can guarantee that 90% or more of the people that walk in the door do not know my music. So when all these old women start trying to sing along or hum to the beautiful songs on my ipod [totally out of pitch!] I want to chop off my ears and stab them in the vocal chords. I can't help it I try tuning them out, but when you hum out of pitch it's like nails on a chalk board to me. So please people that come into the store, i'm begging you to please SHUT UP! kthanksbye.
