Huff A Little Less

Today I was at Adams Fairacre Farms, a local market, picking up a few things I needed. When I got to the check out, I swiped my card. Have you ever noticed all of the swipe machines are just slightly different? So I asked the cashier, 'do I press cancel or enter for credit'. The woman let out an audible and slightly perturbed 'huff' and said, 'you press the 'credit' button.'
