I remember playin life, I flopped the nut straight, turned the royal, had someone betting into me the entire way. Come showdown, he saw the royal, he flipped his lid, starting saying I was a donk, among other things, yada yada yada. It happens, sometimes you're on the winning end, sometimes you're on the loosing end. I've had quads snapped by a royal as well. I flopped a set, turned quads. Found out at showdown they had flopped the royal.
