One marker of whether something is acceptable in society(or having a functioning brain, at times) is to ask oneself "what would happen if everyone did what I'm doing." This applies to most things...littering, talking on speakerphone or blasting music in public, etc. I think this example would similarly fail this test, imagining hundreds of carts piled up somewhere 'out of the way.'
