Sometimes customers do demand “reckless behavior”. Literally millions of people daily drive up to a window and demand (politely) a cup of near-boiling fluid in a flimsy paper cup which they will casually drink from in a moving vehicle - and some (which when discussing millions is a large number) who will even place it against sensitive body parts in what is obviously reckless behavior. Were McD’s et al to _stop_ serving such hot coffee, customers would be livid by the millions.
I agree with your take on that.
And yet in the wake of the lawsuit, McDonalds did reduce their serving temperature to 158 degrees and began using sturdier cups. Yet somehow they still manage to serve that coffee to millions and at least one person here says its still plenty hot.
