Paul, and His Patience

I went over to Amore Coffee to see Paul the other day, and what do I see? For some reason Amore Coffee is back to the completely manual way of processing transactions. If you look close, you can see that Paul could use a credit card machine that makes a big "ka-chunk, ka-chunk" sound when you run the carbon copy over it. There's the fancy calculator, with dual power - solar and battery, and a print out of what the shop offers so he can mark it down with a pen. I'm not sure if this is being "green" or just painful.
