This is very petty, but since you asked...I do not like it when CM's call me "friend". I do not know them, they do not know me, and I am not their friend. Maybe we could be friends, but at the moment, we are not. I'd rather be greeted by just plain old "Hello", not "Hello Friend". And some of the things others mentioned bug me, too. Again, it's something small and not going to affect my day, but I would prefer not to be called friend (at least the non stop "Princess" phase seems to have ended).
Love this one -- now we're talking!
In that same vein, I hate "Welcome Home!" -- it is quite literally not my home.
Like when I ask my husband to do something and he says "sure thing" which actually means "are you (explicit word) kidding me I dont want to do that right now"
