A Las Vegas limo driver is taking an NBA star to task after allegedly getting stiffed not once, but twice during an off season trip. According to the Las Vegas Review Journal,  Washington Wizards star John Wall took a couple of trips during the off season in Vegas & used the limo driver twice, even asking the driver to go back to the airport and get something Wall had left with the pilot.  After returning to the hotel, the driver was told to just leave the item at the front desk.  Translation-NO TIP... The only tip was a built in one for $27.50 for the limo reservation for 4 passengers.  Was the Limo driver wronged or is that the risk you take for going out of your way in that industry?
