Its funny, because after reading the thread I see judgements against the restaraunt ( by people that are not there and not management) and people judging the couple ( who were not there and didn't see what happens).
Judgement happens. There are valid points on both sides, but for those that pointed out we may never really know, are the most correct in any event.
For myself, if a manager felt the need to request that they eat other things ( and we all know there are OTHER things on Atkins besides BEEF) something had to have been up. Nobody needs bad publicity. But I could be wrong in assuming that.
