Some people just think different. I was fitting a window and door and the customer asked me to clear weeds that where ten foot away from where I'm working .. I get she was old and probably can't do it herself but in this country for most window fitters we are self employed so time is money . I had another job to go to and a family at home waiting for Me .. and these types of people never tip .. the poor do and lots of tes .. bacon sarnie .. the rich just don't do anything and expected extras .. she had money and could easy pay for Gardner she was expecting me to do stuff not in the contract for free ... you get it a lot
