"we ordered a pickup, the ordering software had a 20% tip installed. the large sum in the upper right corner did not show it, but a 20.% $8 tip was down to place order ' taste. I changed it to 0% and placed the order. my wife picks her up and they had her sign for the credit card, the $8 drinking money was back. she threatened it at the place. she signed. I get the reception on the line, and they have the TIP back in and have known my children. 20,% we rejected twice."
