Maintenance nonsense

Was at Wendywood clinic with my spouse today. the guy who does maintenance was at the front desk by the door the level of disrespect he has for patients he shouted at us like we were kids. then boom white ppl came along did the same thing we did taking out chairs to seat. nothing was said to them while us we were told in a harsh way to go seat outside. I have never received a bad service from the clinic ever since I can remember till today so furious.
