Chickie brings out my order, and I ask for my receipt, something I never do. I barely glance and see 2 beside each line, as in 2 root beers and 2 bags of ice. I catch chickie before she tries to escape, and tell her that I was overcharged. She takes the receipt inside, and I start sipping on my large root beer. See, that - large.
She comes back out and tells me that the manager can't change it, but she has cash to give me for the second soda. BUT - she needs to take mine back. I assumed they charged me for two large, but no, they charged me for two medium. So to get my money back, I have to turn over the drink I had already been sipping.
They totally knew they double charged me - that's why they sent the large in the first place.
