fired for locking restaurant doors

was given a paper stating restaurant was under a 24hr boil water advisory due to well work on the previous day. water sample was never given to the health dept. later on served another paper from an health dept. official stating anything prepared with the water could not be served. once given paper became overwhelmed with the situation and locked the doors. had reported this to my boss earlier with no response from her. made a decision to protect the guest and the business. fired stating I lost the company money. this issue should have been addressed the previous day before they opened the restaurant back up after creating a contaminate situation the day before. I was the only one held responsible, because of the decision I made to close the doors and discard all potentially hazardous products and the reopen selling bottled products, due to the 24hr boil water advisory.
