Snarky Sunday: Cash or Credit?

I don’t know if I’m on my own on this one, but how frustrating is it when you’re in line at the grocery store, and someone pulls out a credit or debit card to pay for milk? Really? You don’t have a five dollar bill laying around somewhere to cover that? You have to hold up the line trying to figure out if the card has a chip reader or just needs to be swiped by the cashier, and oh, you selected the wrong account, and oops, there’s a pin error, and all I want to do is rip out a handful of change, throw it on the counter, and tell the person to scram so I can pay for my groceries in peace. Just me?
