Fun Facts
Before plastic bags became common, people in Haiti mostly used sacks, which are made out of clothlike materials.
Those bags are heavier than plastic bags and are even more likely to collapse to the ground when they are empty compared to plastic bags
Since Haitians in former times used sacks extensively to store harvested grains, fruits and household items, they were quite familiar with what happened when a sack was empty.
Therefore, it is not surprising sak vid pa kanpe developed over time.
