Have been doing this for years.. by far the best option i have found. You get pulled over for not having a bucket every now and then, but you can just point to the bottle.
Had some female bint say i wasnt carrying enough sand once - i did what any low marker knob would do and quoted my handicap and told her to piss off. Not one of my better moments but provided some entertainment to the playing partners.
The chamois container is interesting... less sand in the pockets...
Bravo on a tremendous reply to the bint, I genuinely laughed out loud. A little ignorant but sometimes you have to fight fire with fire.
