IKEA employees struggle with the difference between a queue and a stack.

When they were going to open up a new queue, instead of helping the people who had been waiting for a while at the front of the line, they announced to the back that a new line was opening. People who had just gotten in line had the opportunity to enter the new line first. The wait was therefore resolved as a stack instead of a queue.

Please FIFO not LIFO.
