I work for a large retailer in California. They are now telling me that I'm not allowed to take my lunch break in the "Cafe" section of the store, even though I am off the clock, not being paid at the time, and am a paying customer (having bought food from the Cafe). They say I MUST eat in the breakroom - my argument is that during that time I am a paying customer, entitled to eat wherever I want, like any other customer. They are now threatening to "write me up," with the possibility of termination. I'm not taking a seat from any other customer, I've paid for the food I'm eating at that establishment...and just want to read my book in quiet. Do they have the right to tell me where to eat?
