There was a coffee shop I used to frequent that used a captive portal for wifi, and the only way to get past it was to enter a 90 minute passcode from the bottom of your purchase receipt. So if I came in there at night after work I considered it basically paying for internet, and getting a free coffee or pastry alongside it. Seemed perfectly fair. I also find it amusing that Starbucks gives you free refills on brewed/ice coffee, provided you go enough to get their "gold" status (usually, 30 store visits a year). They don't care if you camp there and keep getting free refills on coffee. They just care that you do it often.
