Has got to be the beer girls accepting chips? and tipping dealer w/ chips, and getting food w/ chips?  The first one is by far the worst, as many of the people who continually drink are the ones we can get money from.  They end up drinking 3-4 beers/hour (total at the table) which takes an extra 20-30 bucks off of the table every hour.  Would love to see a dealer tip system that did not involve chips, and everyone have to pay cash to the beverage lady.j
