Man came to door at 10pm

I am sure this is nothing more than a one time interaction, but if thought I’d share and get your thoughts.

Wife and I are gaming in our living room tonight. It is 10:00pm. We hear someone cough outside out front door. I walk over and see a figure wearing an orange safety vest. I turn on the outside lights because he’s standing in the dark. Our doorbell doesn’t work so I assume he rang it and stood there for a moment. I see a man in his mid 20s with a beard.

I speak to him through the door - there are glass panels, so I could see him and didn’t need to open the door. I asked him if I could help him. He offers to shovel my driveway for $20. I tell him I’m good but thank you. He offers $15 in a half joking way and I tell him no and good night.

I watch him walk away and then I turn off my lights. I live in West Edmonton/Callingwood.

What do you think? Obviously it’s super weird for someone to offer this at 10pm. Should we be worried he was looking to get details about our house (do we have lights, is our door locked, are we responsive, etc)? Is it nothing?

Thank you all.
