simple answer.
guitar shop guys only know what they are doing after you pay them extra money to do it.
if those dudes spent all day stringing up floor model guitars properly and getting them perfect, they wouldn't have any time to read guitar magizines
or to take thier point of view instead of mine.
dude spends hours working on floor model guitars only to have 12 year old punks come in and monkey around with them and jack them all up. this puts more stress on the guitar shop guy. now working in a guitar shop, (read: not guitar CENTER), and you are a sales guy not the guy running the store or accounting the monthly finance books, this should be the lowest stress job ever.
guitar center runs on commission and gives jobs to dumbass girls with arm socks and bag heads to work the counter with the strings and pickguards, so yea i don't know what my point was going there.... forgot.
