What gets on your nerves or bothers you when playing live?

Mine:

-People spreading their uber poker wisdom and beats/brags to the guy next to them/across from them at the table (start a fucking blog)

-Internet tools preaching about EV, hand ranges, and equity between hands. (STFU)

-The cluessless who showdown their hand like they have nothing or are clueless and have the nuts since the flop
