Meaningless, Extra Work
Why do people take it upon themselves to torment retail workers? It’s no secret that they don’t get paid much, so why make their lives miserable by making them deal with petty torments? In this case, not one but multiple customers took it upon themselves to make some poor employee’s workday horrible.

Whichever customers stacked these baskets incorrectly never played with puzzles or blocks as children, or just plain don’t care. If you’re bored enough to need something like this to amuse yourself, maybe you should consider a hobby or getting a job yourself. Leave the retail employees alone, and give them the chance to do meaningful work.
