Well it seems that most like Cash, and why not.
As for self service I will stand in line at a supermarket and wait my turn at the check out for as long as it takes and will never and never have used a self service.
Once some time ago I was shopping in a new hardware place in Ballarat and was not aware until i approached the check out that the only way to pay for my stuff was to do it my self, Hence the trolley was left abandoned and i walked out.

this was not out of being lazy but out of principle
That placed closed about six months after it opened
So at the end of the day, who decides that we all cant use cash anymore, even at Bunnings today one can pay for the humble sausage with a card or phone
I personally will use my cash all the time, and only recently paid for a $3000.00 purchase in saved cash.
