GuyRule #547.0: Free Beer!!
If anyone, be it a friend, relative, friend of a friend,company rep, anyone offers you free beer, you will take it. You can never, ever refuse it. Even if it is rotten, you will still take it and drink it, 'cause it's FREE.
It's an offence against Guydom to not accept FREE BEER, unless , of course, you are the designated driver. -Rob Marrey
