I hate the tubs with the false bottoms. You know the ones where from the outside it looks 4cm deep but is in fact only 3cm deep. Ben & Jerrys are prime exponents of this as are the hot nuts you get in tubs at bars.
It's not so much the quantity of ice cream or nuts you get, I can live with that. It's the crushing disappointment when you realise you didn't have as much left to go as you thought. That's what I can't deal with
