Not individually but as a function of society. These people keep standards high, even the ones who are unreasonable. I don’t like them and I would hate to deal with them but in contrast they make reasonable people appear reasonable. If there were no Karen’s you might get attitude for asking for a clean spoon. So have some appreciation for these horrible people.
Do they? Have they ever? Have you ever even worked any service position?
If you had I doubt you would find them good for anything but shitty tips, racial slurs, outrageous demands, and the whole heard belief that the entire world revolves around themselves.
