Just to reiterate, when dealing with such (expletive deleted) people, it positively makes no difference if you arrive within the hour, cash in hand: The result is the same.

The essential difference is the difference in people, and unfortunately we will not change that. - Still, I refuse to go all "PC" about it, and so commend the OP, and all the subsequent posters for their rants. (It's healthy to vent a little now and then.)
