If I said it once, I've said it a million times... I don't like to be "greeted" when I enter a store and be coerced into getting into a conversation.
I feel like I get singled out by retail employees who think they are doing something epic by greeting me at the door the moment I walk in, smile at me, welcome me in, and want to chat with me. I am all for being social and being friendly, but I'm not going into a store for chit-chat. And I never know what to say so the whole encounter ends up becoming awkward. It's all so unnecessary.
