He might have had that worm pie someone was talking about earlier though...
How old is he though and is he doing physical work? My hubby takes 6 or sometimes 8 pieces of bread with filling, a piece quiche or sausage roll (or something similar depends what I've baked)piece of cake, some fruit, and a flask of whatever.
He always rings me on the way home and says what's for tea I'm starving but he has to wait as he is usually on bath duty!! Sometimes he has to end something first though as in a snack.
