As a Produce Assistant who puts fruit/vegetables out on the shelves, Nashi pears and Capsicums can fuck off.
My country has strict laws surrounding bio-contamination/importing foodstuffs and Nashi pears (being they're imported) are individually wrapped in tissue paper. Might not sound too bad until you need to put out 5 boxes to fill a display and it takes about 4 mins per box. Doubly so if they get wet because then the tissue paper partially dissolves.
Capsicums aren't so bad on their own, but they don't keep very well (and they wrinkle really easily, which means customers don't want them even if they're still just as good) and when they rot, they leave a smell that is unmistakable and strong.
