After a good lunch, they would not accept their coupon, stating "we don't honor that anymore". When I showed it explicitly states "DOES NOT EXPIRE" on the coupon, they would only offer a smaller discount and 'a discount when I return'. Like there is a snowballs chance I would come back to a place that falsely advertises and doesn't stand by it's word. I ended up asking the police be called to prove my point. When they arrived they stated I was completely correct but they couldn't force the restaurant to be honest, and asked that I come to an agreement with them, which I did. Thank you Dearborn Police!
