A patron walked over to me at the Reference Desk, from the general direction of our print station, and asked,
Can I pay for my printouts with Bitcoin?
I think he was just being funny, but he did it completely deadpan so I wasn't sure. In any case, I told him we do not accept Bitcoin. He then responded with,
Okay, I'll pay with my credit card.
To which again I had to say no, the pay-for-print machine is cash-only. He may have been actually disappointed about the credit card, because he had to go across the street to the bank machine to get some cash. Luckily we have a bank machine so close by, but I still feel bad every time I make someone do this.
Incidentally, we don't accept Paypal either.
