Whether we want it or not?? I see no advantages to going cashless and there's the big privacy downside. Plus, not everyone has (or wants) a smart phone, and credit/debit cards are more hassle than they're worth for small purchases. Hopefully, that day is a long way off.
That having been said, I do use a CC more than I did 10-15 years ago, especially for gas.
I use self checkouts whenever I can, don't understand the hate some have towards it. Is it just that it's &^%$ newfangled technology or is it something else? Never fails I always seem to pick the line with the slowest cashier when I have to use one.
For some reason neither Shaws nor Price Chopper (only 2 supermarket chains nearby) offer self checkout...Shaws discontinued it a couple years back, PC never had it (at least any stores I've been in).
I don't know how age verification works around here...nothing I buy requires it.
