We got a Groupon for this burger joint and and once we went to pay they said they didn't take the Groupon unless it was printed out. We explained that it clearly said you show the app or print it out. They said they couldn't accept anything that wasn't printed out. The manager then came back and said now the 'Owner' said they would absolutely not accept it and that they weren't participating in the Groupon (they changed their story).
The groupon clearly said the Silverton location. They had their location taken off the Groupon site but non the less the way they handled it was very poor. They lost a customer.
In this case it was just plain horrible management. They did a VERY poor job in handling this. We purchased a groupon in good faith, we went to the location that was specifically on the groupon, and the owner was a jerk about it as if we did something wrong.
