I generally make enough lather to cover three full passes, squeezing what is left in the brush onto my hand for touch-up. After that, I rinse my brush thoroughly. Even when I bowl lathered, I preferred to clean my bowl and start with fresh lather the next morning. I can understand being frugal, but squeezing the lather from the brush, with all the stubble in it, and saving it for the next shave is going overboard. Then again, to each his own.
