How hard is it to drink from a bottle of water QUIETLY

[StealthPolarBear]

As opposed to swishing it through your teeth a few times before swallowing?

Maybe they're cleaning their teeth on purpose?

I sometimes swish if I'm trying to get rid of a coffee taste or whatever.

Every time

YABU to complain about water swishers when tea slurpers are still at large.

Oh YANBU. Water swishing through teeth makes me feel quite ill.

No, how hard is it for some people to eat without scraping/squeaking their cutlery around the plate and making that horrid noise - I could vomit just thinking about it! Absolutely no need!
