The few times I've been a few pence short on cash and only had it on card, the till workers have always said not to worry about it. And I've always helped a shitlord out when they're a little short for the bus or washer so I think shitlords are generally decent people and not the anorexic nazis fatties think we are. Of course, the hams who demand money from others tend to be obnoxious and never say thank you which explains the lack of anyone caring.
