This is a good example, but it should be a problem of whoever finds themselves in that situation and not the rest of us. I’m eating a sandwich in Des Moins, Iowa and there’s no reason I should do a mental math of $6.99 + 10% tax + 22% tip. Why not just print the final price? Or at least offer two versions of the menu: for nerds and for the rest of us.
