And I bet there's a decent mall near you with some sort of lounge-type area. I used to manage a retail wireless internet kiosk in a busy mall. We were near the food court, so prime location; we had 1,000 people walking by on any given day. Lots of people plopped down on the couches that were near us; something similar would certainly allow you enough time - they'd often sit there for 20+ minutes.
