    i came in at 8:05 for a blood test. i signed up and waited in a room of around 6-8 people. For the next 3 hours, i watched the entire room fill up and empty out repeatedly while my spot kept moving up from 3rd to 5th and so on. I have missed 3 classes waiting for this lackluster clinic to help me for something as simple as a blood test. why am i getting put so out of pocket? why is there a privilege that is handed out to these people that let them go before me? It’s quite unacceptable really
