This story is one of the weirdest I've heard yet. Everything that went down all because you were 10 minutes early to your appointment is most irrational, immature, and unprofessional regardless of the type of day he was having. Ten minutes early is within a normal, acceptable, reasonable time frame for appointments. I don't blame you for not wanting to set foot in his office again. I'd be paranoid that a sneeze might make him send you packing.

Sorry you have to deal with this bizarre situation. I do hope you can get it resolved quickly in whatever way you need to.
