sit there thirsty

I recently purchased a Groupon deal for starters and mains for 4 at El mariachi, Main Road, Sea Point. It was HORRIBLE. From the moment we arrived we were treated like 2nd class citizens on account of the fact that we were there with a Groupon. It was thrown in our face when we were asked to be seated in the smoking section, we were not allowed to order drinks at happy hour prices and the manager explicitly told us, \ how are we supposed to make money if we allow you to pay happy hour prices for ****tails when you're already here with a Groupon? "Further to that he told us we could \""sit there thirsty \"" if we didn't want to pay full price. Honestly"
