What is one thing that massively goes through you, but far too many people seem to have decided is normal?

The only place to use a toothbrush is the bathroom, but many people appear not to realise this. I keep seing previously normal human beings sink rapidly lower in my estimations by brushing their teeth while carrying on their everyday business, and it massively goes through me. What other minor things go through people or get on your tits in a disproportionate way?
