I generally don't care what people say or how they say it unless they're being insincere or rude. Basically, not WHAT you say but HOW.

I can say that working with the public though, I've really come to roll my eyes with "we're just looking" --- you came in with something in mind. A sofa? Lamps? A recliner? Please don't throw your hand up in the air at me and tell me you're just looking... we do get insulted (awwwwww.... pity poor catnapper). If you share what you're looking for I might have some suggestions to help your search. Many people miss exactly what they're looking for because they say they are just looking (I know this is true because if I can catch them on their way out of the store and ask them, "what WERE you looking for?".... 5 minutes later I'm writing up a sale for what they didn't find )

My husband can not stand the phrase "whatever". Want to take away his good mood and replace it with a cranky one? Answer any question with "whatever" and you've instantly got grumpy-man
