Describe the last positive customer service experience you had?

In the context of a job interview this question is not about "when" you had good service but "why" it was good service. This demonstrates that you know what good service is (and might be able to provide it), appreciate the proper way of doing things, and are smart enough to see though the interviewer's trick question.

To answer it, choose any event and follow it up with a reason why it was good service. Like this:

The last time I had good service was at (Apu's Quicky Mart on The Simpsons) because the owner:

• was friendly
• asked me if he could help
• knew what was in stock
• suggested items that would go well with my purchase
• made change quickly and honestly
• seemed to appreciate my buying at his store
