Bad service

Greetings all,I my wife and I went to McDonald's in Hanover Park, we waited for service and I was one of the employees if there's no one to assist as we wanted to order and pay cash,she said the assistant went somewhere and will come back to assist, after waiting for while again, we left as it seem no one was coming to assist and the others who saw us waiting at the counter to order ignored us.I never want to go back there because I think if it was white people, McDonald's employees would have assisted immediately. Such service in the millennium is pathetic and really unacceptable.
