Triple fail here today.
First they forgot cheese on my wife and sons burger.
Then when they ordered flavor of the day (butter pecan) they brought Olson vanilla.
To top it off the jackass (teddy) who brought them took them back, brought back the right ones, but said "you did order plain vanilla"
To which my wife replied, Maybe your cashier put the order in as vanilla, but I said flavor of the day.
So... Poor customer service today.
