Absolutely! Good design benefits everyone.
I also think it’s less about “good customers” and “bad customers”, it’s more that everyone has a bad day sometimes. Same with driving- I’ve raced for 15 years, had my share of professional training, yet I still do the occasional stupid thing on the freeway. When you get 5 million people on said freeway, there will always be someone near you having an off moment, which leads us to believe “everyone else is a bad driver”.
Sure, there are consistently bad drivers and self-entitled dicks who are consistently rude to service workers, but I do think it’s mostly a numbers thing. David Sedaris not withstanding.
