Agreed, but also I wouldn't get tripped out about it or I'd call Evan on it myself. I would have said,"Hey Evan, what's with the additude? I just asked a question, whats up your ass?" Or something like that.
If I'm in a situation where someone said something that was insulting, or confrontational, I would defend myself accordingly. However, I would not complain to everyone around me, other than a passing remark, like, "That dude was being a dick, but whatever" or the management or whatever. Doing stuff like that to me, is like not taking responsiblility for what happens around you. I guess being who I am, and how I was brought up culture wise, I look at that as being a narc.(Or snitch, whatever)
Added, The reason I look at this this way, is like TorJonson said, so "retailers" use this as bullying, but what about customers that do the same? Most pain in the ass customers use bullying a buisness owner or manager or cashier, as they're way to vent. This has become much more prevalent nowadays. It's a captive audience, that can't talk back, without consequences ocuring. Thats why I have a problem with this kind of complaint. If he said "No I won't cause you suck" is one thing, but to go on a forum and lambast a small buisness owner, is the same as yelling at a cashier in a store.
