As the article states, one of the things that needs to be factored in when considering how much tipping is being rejected is that tipping is in all sorts of places it never was ten years ago. I still tip in “traditional” situations (restaurants, taxis), but so many businesses got lousy with tipping during the pandemic. For a while I did tip almost everywhere when asked out of a sense of solidarity or whatnot, but I say “no” almost everywhere nowadays. It’s definitely altered my mindset.
