Let your friend spit on your food. Then eat it all out, food and spit!
in a foodcourt or anywhere public and clean your paws after meows would be better while eating asswell but not required
Go into a single Restaurant and ask people if you can taste their food. See how many people let you a get a piece/bite/sip ect... Crank up the charm and get that food
Take some food coloring and put some in your eyes.
