My appointment was at 4pm at Columbia mall in MD. I showed up at 4:06 and waited there for 3 minutes for the employee to come to the desk. She informed me that she saw me come in at 4:06 and told me there is only a 5 minute grace period, and that I'd have to drive back home and reschedule my appointment for another day. Are you kidding me? You claim to have a severe blood shortage but will not accept people who show up 6 minutes late? Good luck to your foundation.
