Ugliness was not the issue. It was sales people with body odour and umkempt appearances. I cannot apologize for my frirend's actions as they were not mine. I don't think there's been any bragging. When you're spending money at a place like Louis Vuitton, it goes without saying that it is a lot of money, and therefore the service rendered to the customer should reflect that.
Fair enough; I'm not trying to give you a hard time or anything, as I've had similar experiences (though mine haven't been as bad) and definitely agree that you should be pissed off. As for the money thing, it's fair to say that pretty much everyone here realizes that clothing is an expensive hobby generally reserved for people with money to throw around. On the other hand, casually dropping the fact that you happened to toss "about a month's salary for [the employee]... in the space of about 5 seconds" is in poor taste. Same for your friend's action. It's not the fact that you're spending a lot of money that's irritating, it's that there is the implication that it gives you some sort of moral/social superiority over others. The security guard clearly was a dick and foolish to treat paying customers that way, but there's an air of condescension that I'm gleaning from your post, which makes it harder to sympathize with your otherwise justified complaint. Judging by some of the other posts in this thread, I'm not the only person to get this impression. I'm sorry you got treated so poorly, and you have every reason to be upset, but I think that there are better ways to deal with that kind of treatment. That's all.
