Most of them are from the "ENTITLEMENT CULTURE" - they're entitled to a portion of your income, and they're entitled to act and do as they please. Don't expect any cordiality from that bunch!
I don't, but I was surprised at the hostile tone used on me this morning by someone asking if I could "go to school". They have these training camps going on right now and I can't believe anyone would participate considering the demanding rude approach of the person who called me this morning.
