In college I worked for a few months at a little coffee shop in a mall and it had two cameras: one in the main area and one in the back storage room. They went to a feed that the owner would watch from his house and if he saw me sitting down or doing something else objectionable, he'd call the store and chew me out. I was eventually fired when they had a re-training for all three of us employees and I didn't smile enough during it, according to the manager

Anyway, all coffee shops need to be unionized or worker co-ops; death to coffee shop management
