Why go the extra mile

I made a reservation for today. I bought a Groupon voucher and only once printed did I see the terms of use. Since it was a special occasion I hoped that when we arrive and I explained what happened and asked to accommodate us in private. They would understand and be human. Instead the manager hardly made eye contact. Even though I humbled myself. She refused to accommodate. The restaurant had maybe 6 tables filled. And still it was rather best for her to lose us. We won't return. Not for not serving us, but the rude manner in which the manager did not even show any emotion. A restaurant is good if they have a balance of good food, good service, great admosphere and ambiance. But most importantly hospitality. Definitely not sending your customer packing. Really sad but at least we are spoiled for choice. I'd rather refund my voucher and support someone who welcomes their customers. Thanks for making our day memorable.
