I want to start off by saying that since moving to vegas we have had nothing but good experiences when dealing with Checkers. Tonigjt however was a horrible surprise. It started off alright, ordered two seperate orders no problem. The issues started when it came time for us to receive our food. The woman manning the drive thru window (Olga) seemed to be in a rush to get us out of her sight. I understand that its the graveyard shift but customer service should still be applicable even during the late shift. Second issue was that our order was missing a few things that we payed extra for (garlic dipping sauce and extra ranch) and it was made worse that she seemed mad that we were asking for the sauce that we paid for. Same thing happened with my friend's shake, he got the wrong shake and she again seemed mad we cared enough to ask for the proper flavor. All this would be bad enough but yhe worst was when we got home. We had ordered a large number four and a medium number one. Our friends shake was also supposed to be large sized along with his fries. We noticed that the fries were all small sized and the shake was also a small. Checkers is fast food but it's not cheap like mcdonalds. If you are going to charge the prices you do, make sure your staff is competent and actually cares about the restaurant's reputation enough to actually try during his or her shift. OLGA fails on both accountd and needless to say, we will NOT be coming back.
