A quick question today related to the behavior of individuals who come by your desk during lunch. I often find myself eating at my desk while reading over something. I'm not always doing work, I often use the 15 minutes or so it takes me to eat my lunch as an opportunity to catch up on sports, news or blogs. But it is not uncommon for people to visit my office during this time.
One alternative is to close and not answer more door, but I rarely do that. This leads to interactions where people come to talk to me about something before noticing that I am eating.
If this is a common experience for you, how do you find people react? Do they say they will come back later or carry on as though they would if you were not eating? Does it vary based on student vs. faculty? Your lab vs. not your lab? Etc....?
