I’m thinking in the U.S. and Canada. For example, if you’re on vacation, you’ve checked out of your hotel room and have several hours until your flight, and you have some cans of beer left over. I know you could sneakily drink them in a park or something, but I’m just curious if there’s any way to do it that’s legal.
Not that I know of, only best option I have found is getting the largest coffee cup with top you can find and fill that up with beer. Also make sure there is a place to pee.
