In the UK we use ballot papers.

It's media-driven hysteria again:

1) Probably sales of toilet paper went up slightly, then
2) There was a slew of media reports of people panic-buying toilet paper, then
3) Everyone started buying toilet paper because they thought there would be a shortage because of all the reported people panic-buying it.

Most people just want a normal amount, but are panic-buying because of reports of other people panic-buying. It's self-perpetuating, driven by irresponsible reporters who will make a story out of anything, with scant regard for the consequences. We saw this with the media leaks in advance of the north Italy quarantine, someone desperately wanted to get the story out, and the effect was a surge in people leaving the soon-to-be-quarantined area, so the exact opposite of what was intended. Freedom comes with attendant responsibilities - this applies to press freedom, too.
