Do you allow overnight parking?

I actually have experience with this, any Walmart in the country will let you sleep in their parking lot. Whether that's due to not being able to even tell you're out there, or they have the cool understanding that there are people traveling and there are homeless people. Walmart in Mesa, AZ knew a woman was living in her car in their parking lot, they didn't care. The news even followed her around to tell her story. She would shave her legs in the toilet BARF

Don’t have to ask, you just have to stuff a cash tip for the night watcher in your exhaust pipe. Unless you have an electric car, than you are BANNED DO NOT ENTER.

You have to ask permission from management.

I think it's ok
