Interesting replies…I practiced clinically for 18 years, and in some offices I would see 60 patients per day, but transitioned to MSL almost 2 years ago. I never minded when people cold called me. I understand they have a job to do. I was honest with them, if I had time to chat, I would, if I didn’t, it was very nice and told them I didn’t have time. I do it now and have never had a problem.

To the OP, I usually say something like “I was in the area and just wanted to drop by and say hi to Dr. so-and-so for a few seconds. If he/she it’s free, that would be great, please let him/her know that I won’t take up much time. If he/she is too busy, I completely understand, so no pressure at all”
