Would it be out of character for a chaotic neutral person to just help someone out on a whim?

Sneeze on hanky. Give begger hanky.

GM: You see a beggar in the snow, what do you do?

CN: I plink him in the face with copper pieces while making fun of him.

GM: Dafuq?

CN: Then when I run out of money I grab him and say “okay, it’s your turn, let’s switch places!”

GM: He freaks out and runs away.

CN: I chase him, sword out, and shout “Come back and be my friend you little broke bitch!”

As long as they don’t go from a broken begger voice to an aristocratic voice in half a sentence because of a shit voice acting budget.

i had a chaotic neutral player once that was trying to convince a lawful evil player that it was wrong to kill a goblin when they both work for some guys who were telling them to kill goblins

LE player remembered CN of his alignment and he intantly killed the goblin
