It's called the esky theory.
eg. When you go to a BBQ at say your wife's bosses place.
In theory you will probably only drink 15 to 20 cans.
However, you always cram all 24 into the esky .
That way you have leverage for when she wants fit her bottle of wine in.
If you are a sharks supporter on this forum spend 10 minutes and put a submission in. Writing on here means f**king nothing if you can't even spend some time to support the sharks with a submission.
