Okay, it was a bad experience.
Maybe the food was bad, the service was bad AND there were other problems.
In the heat of the moment, as you are grabbing purses or children in your haste to Just Get Out, Do you tell the manager?
Do you go home and write corporate or Yelp (or ChowHound?) about your horror story?
Does the restaurant get a chance to know the error(s) of their ways?
