Poll: What’s a reasonable amount of time to camp out in a coffee shop?

There is an unwritten rule that by simply purchasing a coffee you are entitled to sit for an indeterminate amount of time inside of a coffee shop. But how long is too long? When do you go from regular morning customer to approaching the legal definition of squatter.

The idea of coffee campers is not a new one, but the ways in which coffee shops are handling customers who view their local java joint as a second home is all over the map. Some places cut Internet, others have taken away wall plugs. But nobody has quite decided exactly how long customers are entitled to set up camp.
