at pinball at the zoo (for the tournament games) , pin bowl and pin wars we have change machines.
we also have quarter rolls pre rolled because some people prefer just buying quarter rolls.
that takes care of the quarters, we are never short on change.
also, newer machines have bill acceptors as well.
if you have imonex coin mechs, you will have very limited coin jams.
coin jams usually exist due to people sticking tickets, straws, candy wrappers and coins other than quarters in machines. mechs don't jam up from using just american quarters.
for anyone who brings games and who doesnt have coin mechs, i provide the mechs. pretty easy.
people pay ZERO to get in, just as papa, so im not sure why someone would frown on entering the facility.
its free to enter, free parking.
when games are on coin play, it cuts down on people who start 4 player games to play by themselves and other situations that create lines and people hogging the good games.
when it comes to counting the coins, use an electronic coin counter.
mine can rip through $2000 worth of quarters in less than 2 minutes.
it's seriously not that hard. when you have a tight staff and good people in your circle, its easy and works out well.
also, for myself personally, i do not get my full $20 or more worth of entry fee per day of any show on the games on free play, esp when you figure in the 25 cent em games.
next time at a show, count up your plays (don't include free games/matches) and see if you break even, or would have spent more/less if on coin play only. Also, even on coin play, you will be able to walk around and catch free credits on games that people leave if they win.
+1 on the kalahari idea!
