One time at my previous serving job, there was a situation with an aggressive customer that escalated and the manager was brought out. The policy for dealing with an upset customer is for the manager to deal with the situation 100% and I was told to go back to work. However, the customer asked the manager to step outside alone. And I felt that my manager's safety was at risk, so I walked out with my manager so I could make sure that the conflict was resolved peacefully. I took it upon myself to go against company's policy and to make sure my manager was safe.
