Not quite THAT bad but I was guilty of buying too many veggies (or salad), only to find them yellowing or (worse) turning slimy in bottom of fridge or veg basket. I am not as bad now because I plan things better now I am not being pulled in as many directions. But yes, a terrible waste.
But what bothers me are those people who throw out food as soon as it gets within sniffing distance of the 'Best before' date.
