I was going to say it wouldn't be a problem but the more I think about it I'm not sure.
I just got this weird vision of spilling some vodka on my hand and licking it off or something.
I'm on the fence on this one.
I think it would probably be fine. If someone wants liquor there are stores everywhere. I guess on that same token, if someone doesn't drink no matter what, they could just see it as work.
