Please please, don't eat in the buffet line. Watching you snack on the food as you go through and licking your fingers, and then picking up the next serving spoon just grosses me out. And if you touch something..it's yours. Don't put it back. If you knock over the extra lettuce, please don't put it back in the bowl, with the fingers you just licked. Also, assume, if you see something off to the side, it may have fallen on the floor. Please don't "help" by putting the item back in the serving bowl. This goes for cruises too..no snacking in the buffet line! And if you did snack, when you go to the self serve drinks...please use a napkin, not the finger you just licked, to push the button.
