I think we all have different ways of dealing with frustration, and I tend to, well, curse under my breath when I'm having a bad day. If someone came up to me and said "Hey, your cursing is (a) annoying and (b) offensive, please stop", I'd definitely make an effort to do so.
(Why is it that so many people with annoying habits tend to deny that they have them or put all the blame on the complainer? "If that bothers you, it's YOUR fault, not mine.")
, maybe we DO work for the same company! Stand up and yell "TRY THE BEAN DIP!", and then I'll know for sure.
