Totally agree: punctuality is demonstrated respect, a value I follow as well as expect. And the esteem value of that is independent of the attitudes/values of the other party. It's important to how I see myself as my best self that I show that respect, even when it's not expected, demanded, or valued by the other person. So I admit I have a difficult time understanding the de-valuing of punctuality by a professional: how does that person define professionalism for him/herself?
