After ordering 2 combos at the drive-thru I pulled up and was given the total. As I was getting my money out I was told by cashier Mia that I would not be receiving my drinks because they had no CO2. I asked if my total would be adjusted because of this and she said that was the price for the combo. I asked her if she seriously expected me to pay the same price for less product. She gave me an angry stare for about 10 seconds and then said she would get her manager. Shortly afterwards the manager came and without opening the window made some adjustments on the register then opened the window and stated my new total. There was NEVER an apology or even any courtesy whatsoever from either of them and the discount she gave me was sixty cents for two drinks! You people are in the wrong business! They both have absolutely the wrong attitude towards the guests that make their jobs possible. Shaking my head in disbelief at how bad the service was.
