Aye, you make some fair points, Lugano.
I am just never comfortable having too much cash on me. There’s also another issue – it’s a hell of a sight easier accounting for card payments than remembering to get a receipt every time you pay cash for a business-related expense. I often don’t get receipts for cash payments (or sometimes can’t get them), so I guess every year I’m a good few grand down in terms of cash payments I’ve made on business, which my accountant is reluctant to let me reclaim without a receipt. It’s life, I guess.
