A beer

You order a beer, and without a second thought or a second to ask what type the bartender pours you and a few others a pint and keep going on his merry way.

"Guess a beer is just auto-pilot for him" you say to yourself before walking off.

You take a sip and recoil from the bitter foam.

"Why do people drink this stuff?" you say as you keep trying to sip it.

You realize he didn't ask to start a tab or anything so its probably best not to go back for another.
