A large drink was missing. I wanted to add these drinks to the food order, but was too late after only a few minutes (strike one). Because I could not add the drinks to the initial order, I was charged two delivery fees, as well as two tips. When the food arrived, I had to catch the driver about the missing drink, a large diet coke. She looked a bit angry, so I told her to forget it. She thed said she would get me another drink, and went to McDonald's to replace my $2.39 large Burger King drink with a $0.99 McDonald's medium drink. This was my first time using this app. It will also be my last time using this app.
