Waiter Or Waitress Question:

Most probably the employer might try to get some negative opinion from a candidate about his / her previous job experience. But the way of handling such question would be that when a candidate is approached by such question then he / she needs to project the positive side of his / her previous job.

And also have to keep in mind that a candidate needs to present only positive side of the restaurant or company even if they are no longer working in that particular restaurant or company.
