Always with my card
Mostly with my card
I can't decide
Quo usque tandem abutere, Trump, patientia nostra?
Still, you should never underestimate the stupidity of the stores/restaurants you shop at. Credit/debit card numbers are written down at restaurants to "charge later." I've seen waiters make mistakes and over/under charged. Skimmers can easily be affixed to card readers, which easily beats the PIN entry.
In other companies, I've seen numbers stored in Excel spreadsheets on the company intranet. Where I working in finance/accounting or others had instant access to hundreds of thousands of numbers and the corresponding names, expiration dates and CVVs.
Always plastic when possible. I hate carrying change around.
I already have one heavy bulge in my pants. I don't need another.
Canadians, like me, took to debit card transactions like crazy when they first came out a couple of decades ago and I think we've led the world at some point or for some time in our use of them - upwards of 94% have and use the cards. I like using cash, when I'm budgeting, because I'm a little old fashioned and watching cash leave my hands and dwindle in my wallet is a little more painful than using a debit card and not seeing the money change hands. I try to avoid credit unless I'm purchasing a larger item, or paying for a pricey car repair, and intend to pay it off over a few months.
A Canadian conservative is one who believes in limited government and that the government should stay out of our wallets and out of our bedrooms.
