A student emailed me a few weeks ago and asked if he could come by and visit my GPR program as he would be in town for that week. I told him sure, and we agreed upon a day and time. When I came back from lunch, he was waiting in the reception area, and my entire staff was snickering. He had arrived in shorts, tee shirt, and sandals. I was polite with him, showed him around a little, and let him speak to the current residents. When he left, one of my residents said " too bad, he was a nice guy". She knew this guy's presentation had done him in.
The students who visit us and appear very serious always dress for business, a suit. Those not as serious appear that way. Even my chief resident, who is the most laid back guy you would want to meet dresses appropriately at the appropriate time.
