A simple "Thank you" goes a long way with me. It isn't in some peoples vocabulary so they are never on my list anymore. That is a huge pet peeve of mine. I try not to let it bother me so much but that is how I was raised & it is hard to change. Also I don't want to change! It is not hard at all to say "Thank you" as I told the girl in the grocery store the other day. That's a whole different post! lol
