An Error In Calculation
Transporting sensitive and fragile materials like glass can be very difficult. For these workers, they learned a valuable lesson on measurements while transporting this glass. They got to the elevator, ready to put the glass in and make their way to their desired floor.
However, they miscalculated the length of the glass and couldn’t fit it in on time before the elevator doors were shut. You can imagine what happened next. The glass snapped in half and eventually crumbled to the floor. It must have been painful to watch as that was time and effort wasted. Thankfully, glass can be recycled, so that probably wasn’t a total waste.
