Reasons you’ve blocked customers

What are some reasons you’ve blocked customers? Here’s mine:

1. They didn’t leave their door code. I called them to ask what it was. They were not speaking clearly at all, and when I asked them to repeat themself, they just hung up on me

2. Also had a place with a door code, but said to call them and they would buzz me up. They didn’t answer their phone or the call box after 5 minutes of me trying both several times

3. It was a hand it to me order. I could hear the person coming to the door, and they kept turning the lock but not opening the door. I asked if they needed help, they didn’t reply. They just kept jiggling the lock for like three minutes so I just dropped the groceries at the door and left.

I think there might be one or two more but I don’t remember for sure
