Taco John's

Went here today and they charged me full price for the meat and potato burritos and they were supposed to be buy one get one for a $1 . When I asked her about it she told me that she can’t do that cause she will get introuble and that I have to say I want it for a $1. That don’t make any sense when it’s right there on the menu. And refused to do anything about it. I’m very disappointed in her actions when clearly it says it right there on the menu. Her name was Nicole s from the lansing ks area
