I'm glad that you had successful experiences with these "delivery" services years ago. I, myself, wouldn't feel comfortable having a car pulling up in front of my house and having a working woman walk up to my door. I'd worry how she was dressed. I'd worry if any neighbors are seeing her. I'd worry that if, I did not find her attractive, she'd cause trouble or ask for compensation.
I guess I'm too much of a worrywart to partake in this kind of activity.
