You can also respond to other people's hates, but it is preferred that you include your own.
I'll start us off with a few:
I hate it when noobs at KSFO think they're in charge of everybody and say things like:
EVERYONE LAND AT KSFO NOW
alfa-j cleard 2 take off
When people say things like this it drives me nuts:
HOW TO FLY A HELICPTR??????????
Let me know what you hate, or just what drives you plain crazy!
