I went cashless years ago. A friend taught me to empty the change in my pockets , and save it in a jar. at the end of the day. Well, now, I've got this huge jug of change. None of the banks around here offer a change machine, and I'm not giving up 15% to use a store machine. I decided to go cashless, and thus "changeless". I honestly don't see the big deal. Yeah, there area few places that won't accept plastic, but even car washes have new machines that accept cards. If you want to slip your grandson a few dollars, give him a store card. You can send an E-check, or use an old fashioned paper check. There's nothing holy about cash. I don't think giving up cash is the first step to enslaving the planet in some kind of nefarious plot. The same concerns worried some, when we came off the gold standard. We went from putting gold coins in the cash register, to putting paper in slots, and now, putting figures into accounts.
And to be honest, I don't think we have any say in the matter. We are going to go cashless, there's no doubt about that.
