While a customer is dining in a restaurant, the waiter or waitress is often the only face the customer sees and is therefore the face that customer associates with the business. Your demeanor will have a huge impact on the business, and as such, employers often ask whether or not you work well with others. Rather than simply providing a yes or no reply, be descriptive in your answer. Something like, "I do work well with others and I enjoy being part of a team" followed by any examples you can provide is often the best answer to this question.
