Chris's hand comes up as they try to grab Jeff's finger-gunning hand by the wrist. More to offer a point of steadying than anything else. Guy seems to be tending more toward the 'falling down drunk' end of the drunk spectrum...

"Fist of all, if you got your vouchers from the welcome committee at Town Hall, they are accepted for alcohol purchase." Chris refrains from mentioning that the bartender is likely to cut a person off before they spend all their vouchers that way. "Second, there's no need to steal from folks. That's no way to make a good impression with your new neighbors."

And third, this guy might even be skinnier than Chris was, at their arrival. Easy to overindulge in that case.
