I like cash, personally. Even Sweden, which was going to be the first "cashless" country, just started wondering whether it's a good idea.
Cash isn't traceable.
Cash doesn't occur a 35 cent fee if I try a buy a 60 cent cup of coffee.
I can still pay by cash when my phone is out of juice.
Cash doesn't get erased if I stand too near some big magnets.
I don't have to remember a pin for every transaction.
There will always be another tenner - if I lose my debit card I'm screwed for about a week.
Nobody can steal the contents of my wallet with a sniffer.
I can't drop a tenner on the floor and break its screen...
I could go on, but I'm getting bored. I know, you're all going to say I'm "resistant to change" but cash... it's just actually quite convenient thanks. (And yes, quite a few of the above have happened to me...)
