I used it last night. At first, he thought it was $1 off. Then, he couldn't figure out how to make a pretzel $1. So, he did 50% off, then 10% off four times. Not the smartest guy, but I did get a pretzel for $.98 + tax.
3/30- My AA at the mall knew how to use the coupon, BUT, they wrote my name down on a sheet of paper - I'm guessing so I can't come back with another coupon. They did not care that the coupon was in my alias name, they just asked for ID and wrote down my real name. I can't imagine them flipping through the pages looking for people with how busy they are.
