There's few things that other me more than what you encountered. I hate the feeling that the employees in establishments are so busy chatting with each other, that they can't be bothered to greet you, assist you or acknowledge your presence. It's as though you are interrupting something. In either case, I just leave. I don't expect a fanfare, just people to be pleasant and do what they are supposedly being paid for. I'm sorry this happened to you.
