Some people like the consistency of a chain restaurant; and sometimes people eat at a chain because others in their group insist upon it. Either way, I think the point is that you can get excellent or horrible service at either end of the dining spectrum. Poor service hurts much more, however, when the price point is very high, and the expectations are accordingly high. I mean, why does it matter if the product is "the highest quality" if you don't actually get to EAT anything??!
If I want consistency, there are many other great options...in our tiny town you have Donut Hole, the Red Bar, Jambone's, 98 BBQ....the list could go on. Chains are good for price only - and you get what you pay for.
But you are right - the point is service and it sounds like the ball was dropped here. Let's keep in mind it was the busiest weekend of the year to date - no excuses but that needs to figure in to the equation.....meaning the exception, not the norm. I would hope the original poster will contact the restaurant directly AGAIN and speak to the person ABOVE the manager there or write a letter as well to voice their frustration, not just post it here anonymously on a message board. Compensation for a bad experience? I personally think that is a terrible business move by any restaurant that does it - opens the door for people to take advantage and you wouldn't believe how many people do once they find out an establishment gives out freebies for a "bad experience". Can only imagine how many would try to exploit it in this down economy as well.
