said by oxwich:This is an example of people pushing the limits. The business offers free wireless for paying customers. If you stay for a long time, you buy another coffee or pastry.
If you don't accept this, then you should surf at home.
What I would suggest to coffee shop owners is offenders be kicked off the wireless router or change the WEP password on a daily basis as is done in hotels.
The best thing to do is print a unique wifi password on the receipt that will be valid for an hour. When it expires you get booted off and have to buy something else to get access again.
