So the deal is, part of my living arrangement is I get a discount on rent if I agree to work part-time (10-12hrs/wk) for my roommate's delivery business. This wasn't a spectacular deal for me, but I was desperate to find a place and it was this or live out of my car. I DO get paid about $4 per delivery, and am allowed to keep and tips received (not that anyone tips in this college town. Maybe 1 in 10.) My main problems are:

I am partially disabled after a motorcycle accident. I had no insurance, could not afford treatment or rehab and have had pain and difficulty with an ankle and hip ever since. Constantly hopping in and out of my car to grab orders and walk to people's doors or dorms in sub-freezing weather makes my life unbearable. As in, unable to walk upstairs at home to the only bathroom, or sleep normally. The roommate knows this.

The other problem is that when I'm doing deliveries, I can't work (I rideshare fulltime) because instead of doing a day or two of solid delivery work or a couple hours a day throughout the week, he spaces out the deliveries, changes the schedule multiple times every. Single. Day. so I'm working for him 25-35hrs/we instead, and I can't accept uber fares on the chance I get a long ride or he scolds me for "ruining his business". Of which he has 3. Three business he is running (poorly) all at once.

TL;DR: I'm forced to deliver food with chronic pain/mobility issues, so I avoid getting out of my car and make customers come to me, in attempts to keep pain manageable. I can't afford to move, or I would in a heartbeat. AITA?
