There's a moment that passes by where Cooper just stares at the idiot who decided to decorate the floor with his drink. Then he hops off his stool and draws himself up to his full height....which doesn't really do much in the way of intimidation, seeing as how he's only 5'6". There's a glint in his eye that doesn't bode anything well for Trevor. There's still a smirk on his face as his voice goes soft and low.

"You've just given yourself two options, pal. You can buy a drink t'replace the one you just wasted or I can take it out of your hide. Your choice."
