I once was at the Starbucks in Stratford-upon-Avon with a few friends, and I took the seat in the comfy chair in the window, while they took a normal table. They had to order something every half an hour or they'd be kicked out, while I fell asleep in the Starbucks window for nearly four hours straight, with nobody bothering me in the slightest.
Yeah, that doesn't really have anything to do with the OP, but I wanted to share that story.
