Thinking you're really going to quit smoking and drinking on a 16-day trip, then raiding my rollies, beer, and booze.
Your muddy feet in my boat and on my decks, especially at night when you're looking for something that's not in my cooler.
Setting up your camp (always in the primo spot) before the boats are unloaded.
Being first in line for anything.
Thinking you deserve a cut in the trip cost because you're a "safety kayaker."
Leaving stuff you need during the day in your drybag and expecting me to undo the load so you can get to it.
Tying your shit loose and dangerous.
Sending my cast iron through the dish line.
Pouring water into the firepan.
Clipping your lifejacket onto my bow line.
Setting a rimshot or even missing the hole on the groover and not cleaning up after yourself.
Stuff like that
