This would be really neat, however it's not trivial to sell those everywhere. If you're lucky to live in a country or even city where they can get those to, you're golden. If you don't, you're screwed.

Unfortunately, as much as I love the idea and tech behind Monero, actually accepting it is not practical at all, as the coin is used a lot for criminal stuff and is thus very strictly followed by many agencies. We don't know if they can break it, but even they don't, businesses can get a rough treatment just for accepting Monero. It's perfectly understandable if they'd rather not do it.
