Went in this past Saturday to redeem a Groupon I had purchased. Was told by the cashier that they did not accept them. I politely asked for the manager and asked her why they did not accept a Groupon for Dunkin Donuts, as that is where we were. She said that they were not participating in that promotion, and I asked why, to which she had no answer. The I proceeded to ask her what Dunkin Donut locations were participating and she said she did not know. She she has said had quite a few people trying to redeem the Groupon. How can you be a manager with absolutely no knowledge of your business? I will not be coming here ever again !
