you respond calmly, politely, and try to give them an estimated time to wait.
Sometimes, having a customer who is extremely upset due to the long wait time is unavoidable. When running into long wait times and delays, try to calm your customers so that they don’t get angry and leave. You have to address the issue and apologize for the inconvenience and explain what you are doing in order to lessen their frustration. And also, offer them comfort and give freebies to compensate them. You have to approach your customer in a polite and kind manner and never lose your patience especially when your customer becomes frustrated.
