Rule #7: Always observe the color of draft beer. If you choose a bar to be on your "Favorites" list, it's worth choosing a bar that has good draft beer... If a bar has good draft beer, and not watered-down piss -- then you know it's not a clip joint. A perfect pint is always nice, but even better is a pint from a perfect pitcher... Now if it's a good bar the pitcher will be glass (not plastic) and it will hold 4 pints... Here is a picture of a full-glass pint with good rich color... If your pint doesn't look something like this, then leave immediately.
