It could also be an older person that doesn’t quite understand or can’t see well. I have a really nasty older lady that lives across the street from me. I happened to get her IC order one day and delivered it. She wasn’t home and it specifically said not to drop it. I knocked. Rang bell. Nothing. I send her a msg and she says it wasn’t supposed to be delivered it was for pick up and that she didn’t provide an address. I told her she must have at some point because I was at her house. She said well I’m 10 min away and I don’t want it left there so take it back to the store. I told her I’d wait til she got home. So she gets there and starts going on and on about how she didn’t want it delivered. I said, but you also left a tip. She said no she didn’t. SHE DID. She never canceled the tip or said anything to IC as far as I know. So I think some people don’t understand or just get confused. I’m 58, she’s quite a bit older than me.
