I'M NOT LETTING YOU IN
Meals on wheels guy wanted me to let him in. Not doing it. If the guy doesn't answer the buzzer he won't answer the door more than likely. We are not supposed to let people in unless they are here for us. No point in a locked door if you open it for everyone. However called them to check on the guy, not like he went for a walk.
A while ago we had some shabby looking dude buzzing random apartments. He would say his friend was not answering and he wanted to go check on him. Again, if he is not answering the buzzer, 95% chance he ain't there. This moron was doing it for days and when it was my turn I went down and took his photo with my phone and told him I was going to give it to the cops. Never came back.
