I stopped to get gas at the Costco in Morena today. The line was short, so I was jazzed about that. As I waited, I noticed a couple of people wearing orange/yellow vests walking up to the cars in line. I assumed they were Costco employees since they had clipboards and were talking to drivers. But it soon became clear these weren't employees at all, but some kind of solicitors. They were going car to car, which held up the lines and distracted people from pulling up to the open pumps. I'm not sure why Costco didn't ask them to leave. Don't be fooled by these guys. Costco put up signs saying no soliciting allowed, in response... General bummer.
Costco isn’t the landowner, they only lease the building and the parking g lot is common space. Only the landlord can kick someone out of the lot, or the police if they’re breaking a law.
Actually, a lessee (the entity leasing the property) can trespass people from the property in their possession. This usually would include common areas such as parking lots, which is why they’re allowed to put things like cart return stalls and gas stations in those parking lots.
