Don't worry, just make sure you understand what expectations customers may have when they come in. Then find a solution that will make them happy.

If it's a timing issue - coupons for dinner, instead of lunch - why not honor them anyway?

If it's a major, costly mistake, have your frontline people explain the situation - but offer something anyway. Perhaps a free appetizer, desert, or 10% off their meal.

Most people will appreciate the predicament your in. They'll also appreciate your efforts to make them happy.

Remember, the most cost-effective advertising is word of mouth. But nothing can do more damage than a dissatisfied customer with an extensive network and a big mouth.
