Who saves money with a restaurant coupon?
In a failure to think of a better title question... see above.
But here's the question in full: Two couples or a group of friends go to a restaurant and have one bill presented. One couple or group member brings in a coupon. In terms of etiquette does everyone in the group save the money or does only the individual/couple?
Does it matter if the coupon is $X off or X% off?
