extra tip : buy 1.5L distilled / mineral water. but dont drink
it in one go 
That's a great idea...but here's a better one.
Buy only when you have empty bottles.
Then use the empty bottles to split the 1.5l bottles.
No point getting one poor fella to lug everything.
And...sigh, I don't understand why some simply loves to
mock, call names, etc etc. I get the kick outta what happened, but
rest assured I don't find it that fun calling people names.
Still...
