Casa Maria Authentic Mexican

I didn't like the sweet tea and asked for a coke instead and when the ticket came she charged us for my wife's drink and both the sweet tea and the coke. When I went to pay and I asked her what the three $1.99 charges were. She said for the three drinks you had. I had to explain that I wanted the coke instead of the sweet tea since I didn't like it. She didn't understand but took it off our bill. She just didn't seem happy about it. I didn't think I would have to explain that I didn't want to drink sweet tea and coke when I told her I didn't like the sweet tea in the first place and wanted a coke.
