when my friend planned to meet up with a guy who wanted to take photos of her feet, she met him first at a food court with her girlfriend.

when they met for the photos I was there as well as her gf. we left them alone but --and this is what I think is a good idea under certain meeting circumstances-- he agreed to give his keys to her gf.

He was okay... but had that not been the case, he couldn't drive off with her.
