It cost you $6.50 to learn exactly what to expect of people when you supply the money or tokens to play your cab. There are several suggestions given here. I'll list them - kind of like those "good / bad" lists you make when trying to decide something.
- make them use their own quarters & no coindoor key
- ask for the money back
- cover charge (booze)
- get better friends
- "next time" quarters are on them (although if you can't ask for 'em back....)
- put a "credit button" somewhere(s) on your cab
- use tokens, pennies, nickels - anything less expensive than quarters
- don't let people play it
If you can't ask these people to put the money back because it's truly ticked you off, you absolutely WILL NOT tell them that "next time" the quarters are on them or that there's a "cover charge". Since you weren't home and they did this, they prolly WILL take whatever else you use instead of quarters, for whatever reason they are missing now. If you're a believer of the "just can't replicate the "feel" of the game if you aren't pumping in the quarters, then you simply MUST lock your coin door and hide the key since you evidently will find an empty hollow point in your heart by installing a credit button.
You cannot always vouch for the people who will be coming by and playing your games. Therefore, if you don't wish to remove the keys, and you feel some overwhelming obligation to supply the money to play, you're a sap "hoping" the same thing won't happen yet again. GW said it best when he said "Fool me once, shame on you, fool me twice....fool me.....well, we won't get fooled again".
You only have three solutions. One will get you thrown in jail.
- Tell your "friends" to start bringing their own money and they need to replace yours
- Lock it up and take the key, force them to pay to play
- Grab whatever is thick and of sufficient weight, and set about educating them about the punishment for abusing your generosity and the price they'll pay if they do such a thing without thinking again.
My personal choice would be a combination of the last three.
