Is it illegal to bring and use a beer funnel in a public bar, provided you only use the beer purchased from that bar? Is there a national law, state law, or would it be the individual bar's decision?

Ask Gothamist doesn’t know of any national, state, or local laws that would prevent you from bringing a beer funnel into a bar (and we’re sure our readers will correct us if we’re wrong), but why would you do this? Beer funnels are strictly for frat houses. No self-respecting adult should be bringing a beer funnel to a bar.

We wanted to get a second opinion on the beer funnel issue, so we asked our favorite bartender about it. “Beer funnels would definitely not be allowed in my bar,” said Suzy, who bartends at Boat in Brooklyn. So it seems it would up to individual bars to enforce a no-funnel policy. It’s never a good idea to piss off the bartender, and we can’t imagine any bartender in the area who would welcome beer funnels at the bar. If you really want to drink beer through a funnel, funnel away in the privacy of your home. But if you’re going out to a bar, have some class and leave the funnel at home. And please remember to always tip your bartender well.
