McDonald's, Cary

Drove through the McDonald's on Maynard Road around 4:30 PM yesterday and ordered a large iced tea with lemon. Waited about 5 minutes before ordering and another 3 minutes before paying. Gave cashier a $5.00 and tatal bill was $1.08 She gave me back $3.38. Finally got her attention and told her the amount was short. She took all of the money back and gave me $3.62 and gave me a dime at a time until I had a total of $3.92. It would seem that the cash register would tell her how much change was due if she rang the sale up or she was trying to short change me hoping that I would not count the change. In addition. I finally got the iced tea with no lemon. She evidently needs more training. Bad experience!!!!
