Maybe you should start doing that mate. Even it out a bit, you know?When you buy a bag of chips for lunch and all the lettuce in a plastic box lunch eaters think its fine to say " ooh can I have a chip? Can't resist the smell!" Times that by 10 -15 people and you have none left! Sod off it's my lunch!!!! Do I beg for a spoonful of cous cous off you? Ask for a cherry tomato? A slice of cucumber????
