Noisey eaters.....

Doesnt it get on your nerves lol... how do you cope with someone who's a noisey eater even when there fat gob is shut? Dads sat next to me shovelling Pizza and Garlic bread down his neck into his fat stomach... when he clearly doesnt need to. He's such a noisey f'ing eater though, told him before and he's driving me up the wall... that plus the huge belch afterwards... arghhh
