I usually have my wallet with me, so I can use my debit card for most purchases when going out. But during school, I usually buy snacks and soda from the vending machine. For that, I use apple pay when my dad gives me money on it, or my debit card.
I never have cash nowadays, the last few times I had it was a payment for an art commission. I usually fly through it quickly when hanging out with my friends... But other than that, all I have is a few pennies...
So overall, I use my debit card the most, but I'd prefer having cash at some point for the vending machines at my work that don't take debit or apple pay.
