I've always been an advocate for paperless and cashless society. In my office, my colleagues know I have soft copies of almost any document and hardly ever keep hard copies unless I am mandated to which usually gets to my nerves.
This is also my behaviour towards cash. I buy almost anything online with my debit card, pay for my cable, for flights, use PoS machines in boutiques and shops and even recharge people's mobile phones directly online.
I can't remember the last time I was at the bank because I've not had a reason to for a while. I use any online payment platforms you can think about. I use and love mobile money and I get angry that I can't use PoS in the general local market and the filling stations. So, these are the only places I go to with cash.
