We mention how we drove 2 hours and our parents are inside the buffet. We go through it again saying how she has a picture, he says physical ID, which is fine. Manager comes to us shaking his head saying no. The doorman meets the manager ahead of us and says 'they found a loophole with parents and our trying to trick us'. 3 in suits and 4 in security uniforms and form a border around us. We requested to speak to the manager to try to explain our case. He said thats only for minors and we pointed out how the whole point is to avoid people underage so you need ID and people that cant be proven to be 21 can be escorted by their parents, as per their own rules and a giant banner right behind him says. The doorman didnt comprehend this concept. Signs said ID to verify 21 or older so we said since you cant verify shes 21 then let our parents come to the front and 'claim' her so she can just go to the buffet. We were meeting family, our parents and aunt and uncle inside at the buffet. We tried to reason with the doorman and say how we drove 2 hours. They needed to check her ID and wouldnt accept a picture which is understandable. Came with my older sister who forgot her ID. The casino is the only one for quite a while so everyone stuck coming here.
