So, we recently had a problem with our phone lines at the shop. The lines somehow came "undone" and had to be re-wired. I don't know what happened, but it's all very clear to the phone repair man and I didn't ask, so as not to annoy him. He was, in fact, very nice and the second guy who came out (due to confusion on the part of customer service) was just as friendly.
The whole point of this story is that for about half the day we got to use the old fashioned credit card sliding contraption, which was lots of fun. I must say, it was a big relief when we were able to go back to the quick and normal way of processing credit cards. But for a couple of hours there work was pure, novel fun.
