I've went to GameStop and specifically picked a copy with the manual in it, only to have the bastards *TRY TO* switch it out with another copy that didn't have the manual.
Yeah
I've had certain employees at certain stores *attempt* to do the same thing with me.
I can be pretty verbally scathing, sarcastic, acerbic, condescending, angered, insulting, demeaning, loud, nasty, and just plain old mean (yes, all at the same time:) + I'm over 6 feet, decently-built, and (I've been told that I) come across as looking/coming-of as being pretty intimidating/menacing several times...
...
TL;DR = I've yet to have any one employee ever try this on me more than once
