They don’t grow here, so they are not cheap. In the 90s “Southern fruits” were orange and banana, everything else from outside Europe was too expensive for the common folks. Before the 90s you couldn’t even buy any of that.
Just looked it up on some online local shops, the price is 2-3 USD a piece. Not a kg, one fruit.
4 hours missing, what were you doing that time? 8 hrs of sleep should be enough, than you have 16 hrs to watch the screen, those are rookie numbers.
