People who start their meal before everyone else's food has arrived. It gives me the rage (even though I'm not sure why!).
My lovely inlaws all do this and I quietly seethe blush

It's just considered good manners to wait for other diners. If the delay was such that there was a risk of food becoming cold, you would probably get away with 'Do you mind if I start?'
