Begin by telling the interviewer that thankfully the majority of customers are pleasant to work with, and the rude customer situations are typically few and far between. Next, say to the interviewer that you understand customer service means always having a smile on your face, cheerful attitude, and pleasant demeanor. Tell the interviewer that you would continue positively interacting with the customer even when they were challenging. Share that you never know what type of day that customer has had, and you smiling and being pleasant might be just what they need to help them turn their day around!
"Thankfully insulting customers are not an everyday experience in my current place of work. When I do face a rude customer, I kill them with kindness! If I am still smiling, cheerful, and maintain a positive attitude, I will be sure to throw anyone unkind, off of their game!"
