mmmmm... Now I need something sweet...
Whit 4 players we nearly ran out of coins just befor the 2nd show, and did run out befor the 3rd show.
But then nobody flipped any performers until the 3rd show, so we all had to pay quite a lot of salary.
Whenever something is about to run out (like money in your case), please use bottom to top priority. If this gets really hard for you, you can always use a house rule and assume money is infinite.
