I love beer and I make no bones about it. As old Ben Franklin put it, "Beer is proof that God loves us." That's why I don't understand people who would waste beer.
Let me tell a story that illustrates where I'm coming from.
When I went to college one of the first side-jobs I took was working at a package store (that's what we call liquor stores in New England). My job was to stock cases and handle kegs - incoming and outgoing. On my first day someone brought back a keg and I tried to refuse it - because it wasn't empty! How could you return a keg if it still had beer in it? In my mind that was just wrong on so many levels. That was the day I learned that not everyone shared my beliefs about wasting beer.
One of the biggest ways beer gets wasted is when you are at a bar or a party and you put your beer down - you go to pick your beer back up but suddenly there's more than one. Which one is yours? You don't want to grab someone else's beer - so you just go get another while your old beer sits there wasted. That doesn't happen to me because when I open a can of beer (or a can of anything else for that matter) I automatically turn the tab to the left. More than one can sitting on the table? Mine's the one with the tab turned to the side. [If it's a bottle then it's always in front of me or in my hand.]
Anyway - I love beer.
