Please settle argument/check I'm not going mad.
I remember late 90s/early 00s -and being very financially irresponsible- that you could get cash from a transaction on your debit card. E.g. you'd buy chewing gum for 30p and get £30 cash which you had to sign fir on the receipt. The best bit was for some reason you could get the cash even of you had no money in your account because there was a time delay on it processing.
Friends same age not only do not remember this, but a bank working friend says it would have been impossible. But I CLEARLY remember doing it
