Subway complaint: Racism

I would first like to start off by saying before I entered the store people were in line just standing by the register. Is was a good 10 mins when I asked the person in front of me what was the problem. I was told something happened with register and they could no longer take swipes. They never announced that as other customers entered the store so I told them. The workers are from Hispanic orgin and the young man that was at the register was Hispanic also. There were 3 other people who food was prepared and waiting to pay. They were all waiting paticelly for the problem to be resolved. The next custmer was a black man and his two kids. His order was already bagged he was just waiting to pay. We have all been in the store now for 20 or more mins. The worker handed the Hispanic man his food without paying. We all witness it. The black man asked if he too could get his food and he was told that the Hispanic man paid. That was a straight LIE. It is a shame to treat people that way. If my mom who has diabetes was not with me it would have been a different scene. We had cash and my mom needed to eat something.
