Maybe it's just me, but I've never been tilted when somebody wins a big pot and leaves, regardless if his cash-out included my former money or not. It's now his, to do with what he wishes. However, I don't expect any crap when I decide to leave, either. I do always respect cash-out advanced-notice rules/etiquette, and expect others to do the same. But tilt? Nope.
it certainly doesn't tilt me, but it does show a general unawareness of poker etiquette to cash out immediately after winning a particularly big pot.
