In early years with my former T I would sometimes wait 30 to 45 minutes but she had to travel to get to her office (it was her second office) and part of that involved going through a mountain pass and you just never know how the traffic is going to be. So I would sit on the floor outside of the office (how annoying--no bench) and eventually she would arrive. As the years went on she got better at not being so late but would typically run 10 or maybe 15 minutes behind. With my PDOC I've waited over an hour but I know sometimes they have to fit someone in who is in crises. I don't mind. I know he would do it for me because he has. But normally I just have to wait like 15 to 20 minutes. I'm at the end of the day so I know he will eventually get backed up. I need my meds so I'm okay with it.
