You see co-worker being rude to a customer?

If I witness a co-worker being rude to a customer, I would first intervene discreetly to diffuse the situation, perhaps by redirecting the conversation or offering assistance to the customer. Afterward, I would privately address the co-worker to express my concerns about their behavior and its potential impact on both the customer experience and our team's reputation. It's essential to promote a respectful environment and ensure that all customers feel valued. If the behavior persists, I would consider discussing it with a supervisor for further guidance.
