They issue red/yellow cards in soccer I think the very same principle can be incorporated into many aspects of every day life.
Here's one example to save the barworker the hassle of having to explain why he/she is asking a patron to leave, or wanting a last drink when they're already intoxicated. Issue a yellow coaster/beermat with their drink which the doorman can clearly see and so can everyone else.Receive the red coaster and "that's your lot"!
I think this is in the right place.-- skinflaps, Sep 30 2002 Yellow croissant!-- thumbwax, Sep 30 2002 [Amos Kito] your link has me a tad confused or am i missing the point here? or should i say thrown off a twisty track.-- skinflaps, Oct 01 2002 I imagine that most drunken barflys would accept a card system better than a word from the landlord. Everyone knows that refs don't change their mind.-- wagster, Mar 08 2005 Another good idea from the past! +-- xandram, Apr 30 2013 Yep, random button is cool. If farmer John was, is still here he'd turn this into a bar sprung drinking driven coaster clock.
