A mother and daughter walk into a bar...
Mom says.. "Did you see that dirty look the bartender gave me? "
The daughter says... "She didn't give you a dirty look... you had it when you walked in"

Disclamier... Not a comment on anyone's post, just maybe a better way to look at what sometimes seems like a slight from someone else.
I find a friendly smile and warm handshake prevents close to 100% of these type problems.
