Do they allow overnight truck parking?

Theres a dead end street next to Walmart and on street parking at shopping center across the street

I work there, you aren't supposed to park in the lot as a truck unless you're shopping and leaving or if you have a delivery for us. We are NOT a truck stop.

Yup allllllll nigh loonnnng

I've seen trucks in the parking lot late at night but I'm not sure if they allowed or not. I would have called them and ask them

I park anywhere they dont want to lose a sale
