I can tell you that as a parent, and a collector- I take my kids to a few local arcades and send them off with about 10 dollars in nickels- this is a “nickel cade” and although a few games really are a nickel many are 2-9+ nickels. This particular place happens to have about 12 DMD or newer games including MMr (9 nickes a game!!! Woot!!).
My kids will burn a pound of nickels in minutes playing vegas style redemption games that reward them with 100 tickets streaming onto the ground. Then they turn in their 400-800 tickets an hour later (10-15 dollar cost plus 2.50 admission) and purchase a 50 cent plastic piece of shit.
Luckly- I can get my daughter to play a few MMr (she loves castle multiball). But yes-
I have the run of the 15 or so pins- I walk 10 feet to the left and I can barely move in the crush of children and idiot adults playing the vegas style redemption games. I swear to god- there are adults that will play for friggin tickets and do so “competitively” to the point they will jump in and work a gane if a kid leaves a “valuable” prize in an easy to get position.
I don’t inderstand it, and it pisses me off a little bit, and I have to restrain myself from draggin my kids away from the garbage and “forcing” them to learn a true skill- like robotron or pinball 
To each his own- but I have true empathy for you trying to turn this into a business. I don't know how to get people to realize that arcade games and pinball games reward good play and are FUN! I do NOT understand the obsession with tickets. We talk about the fact that what my kids get is total garbage, and they completely agree and will even laugh about it- but human nature loves instant gratification. I have to admit... I have been known to load 50 nickels into a ball drop game and work to get my kids over the line for the last 300 tickets they need to get X or Y prize. So I get it- I just wish I did not get it and those games were gone.
I probably am too old to get the new redemption game model- but not really, its has however been a LOON while since I was 9.
Good luck and best wishes. I would dine at your locations and play your games. But I am only one.
