Many salespeople aren't friendly until they're sure you're going to buy something. Usually salespeople are friendly but sometimes I get the "I have more important things to do" vibe. Its either I'm completely ignored or they are annoying as hell. Oh and I don't like how sometimes they just pop out of nowhere and yell "HI.". When I go shopping I like to look around and not have salespeople tell me what I should wear or what looks good on me.
