Always play cash games with dice chips this way. We have like 4 sets we take to the game and just combine them to have enough chips. Of course the chips suck, but it usually takes about 10 hands and everyone knows what chips are what. Also make sure the denominations are selected correctly. I have played some games where they play fe .25/.50 and they have a .25 denom and a .50 denom and a 1 and 5. In this sense it gets confusing and annoying.
Edit: Even as people get so drunk it takes them 10 mins to play a hand with 5% equity, we still don't normally have too many denomination problems.
