My last office job involved my desk being 7 feet from the entry door to the building. We had codes to get in so anyone not employed there had to knock and it was on me to get up and figure out who they are and decide if I could let them in. Half the time this also involved me tracking down someone else in the building to see if they were expecting said individual OR I had to have the back and forth discussion with said individual that no we don’t want your services and point to the No Soliciting sticker right on front of them on the door. This definitely took away from my productivity.
