text: our driver seemed nice enough.   he was a heavy set, young black man.  he drove us down the strip and pointed out some sights and gave some advice on where to go and what not.  but when we were dropped off at our hotel a young couple collected there bags and didn't tip the driver.  he yelled at them and called them names loud enough for everybody to hear.  he continued this until the couple had entered the hotel.  meanwhile, my boyfriend and I, along with another gentlemen, stood amazed at what we were seeing.  When my boyfriend gave him a dollar tip, he rolled his eyes at us.   On the shuttle ride back to the hotel, a different driver made sure we had tip money before he let us on the bus!!!  Tips are supposed to be earned through good service, not bullying.
