I think someone has been sleeping in their vehicle in the parking lot of my business- what can I do to make things more comfortable and inviting?

Basically title, I’ve seen the same vehicle parked in front of my business on my security cameras or when I arrive early in the morning to open. They’ve been no trouble, very respectful actually. I feel for someone living in that situation. What are some things that I could do to make their live easier? Keep in mind it’s been in the single digits the past week
