How do you answer how do you handle guest complain in a job interview?

You probably know how to deal with unhappy customers already.

You acknowledge the problem, apologize for it's occurring, listen

to the customer's issues and opinions, and ask him how

he would like you to resolve the problem. Do everything you can to

retain a customer.

That's pretty much by the book. Any customer service class will teach you

that stuff. If you can recite it to an interviewer, you will have satisfactorily

answered his question.
