My angst on this subject seems to be pathologically unlimited.

1. Chefs on TV sticking their fingers in the sauce to taste or using a spoon for two tastes ie not discarding spoon after each taste.

2. Those lovely people that walk around the supermarket (I hate to be contentious but they always seem to be fat women with screaming children in tow) who insist on taking a grape from a bunch of grapes that they don't buy and sticking the grape in their fat mouths.

3. Those people at the breakfast buffet who insist on taken a rasher of crispy bacon from the bain-marie and sticking it straight into their smug gobs. And then another grape from another bunch ...........

4. Those who think they look more savvy if they pick up fruit and veg from market stalls (foreigners love doing this in French markets in particular - but it is escaping .....) and sticking it on their sweaty, snotty noses to sniff it - then pretend it isn't good enough (they know what they are doing you know ) and then stick it back for someone else to eat. They like doing this with peaches in particular.
