You just don't like to carry a debit card? It's cool, I'm just curious. Personally, I hate carrying cash. I drop it pulling it out of my pocket. Yeah, I know, wallet, but I've never gotten into the habit of putting pocket money in my wallet.
do you keep your slips and reconcile after each purchase or at the end of a period of time? It seems there's a presumption now that you don't get a receipt when you use a smartphone or a debit card. To me, that's asinine. I want to know my balance and whether my outstanding bills are covered. I don't want to slip below my minimums. I reconcile to my withdrawal slips and keep a register. I avoid Sweetgreen precisely because of the no cash policy around here (which they don't do outside of the DC area).
