You guys got really nothing to complain about. Try working in a psych ward where you try to help people thet are mentally unwell who believe there is nothing wrong with themselves and that you are lying to them.

I put up with this every day so when I go to a shop and cop some idiot behind the counter (and believe you me there's a stack of them out there) then god help them. I truly respect the professional non-bull**** salepeople however because there are a lot of nasty customers out there as well.
