Sonic Drive-In review: service

On the 17 of september I ordered an unsweetened iced tea the order taker put sweet tea I corrected her to make sure it was unsweetened then she ask an additional three times before changing it to unsweetened so I thought we had it right. The server who brought it to the car said here is your unsweetened tea in a very sarcastic tone. The first thing I noticed was there was a small leak in the cup then when I took a drink it was very sweet. No complaining about the food just very poor service and very sarcastic servers there have been other incidents at that sonic with service which I have over looked but this was the straw that finished me using the sonic in idabel.
