My commute was particularly horrendous on a morning earlier this week, so I broke up the trip with a stop into a Caribou Coffee coffee shop in Edina, MN where I figured I could wait things out while checking a few emails and enjoying a cappuccino.
Caribou was a little late to the caffeinated WiFi scene, but has since jumped in with a free WiFi offering. However, there’s a twist. It’s only free for one hour and one minute:
After selecting the network and logging in, the following screen pops up.

That seems reasonable to me. If you’re not buying anything, get out. It is a business after all.
I haven’t encountered this particularly policy on previous visits, so wonder if this was put in place after encountering too many WiFi squatters?
