Why should bags of bread never be stacked on top of each other?

Bags of bread should never be stacked on top of each other primarily because they are fragile. Stacking can put unnecessary pressure on the bags, leading to potential damage to the loaves inside. This could result in squished or crushed bread, making it less appealing to customers. Maintaining the integrity of the bread is crucial for presentation and quality when serving.

While concerns like staleness, loss of flavor, and pest attraction are valid in other contexts, they do not directly address the immediate issue of the bread's physical condition that comes from improper stacking. Proper handling ensures that the bread remains fresh, intact, and visually appealing, ultimately contributing to a better customer experience.
