I think that the DP would still be worth it....but I was thinking the same thing as another poster, the poor staff maight be making even less because some people dont go by 15 18 or 20 % they only tip one flat price no matter what the bill is. I have seen it. I have even seen people post here that say they tip 1.50 per person at the table! (sorry I guess this turned into a mini rant )
