I think it is often easy for people who prize organisation, punctuality, etc, a rather orderly lifestyle, to condemn and attach negative "motives" to others who may very well march to a different drummer. Different does not always mean disrespectful, or lacking in consideration, merely because persons are casual about time/tardiness. If fingers were pointed at punctual people, and labels such as intolerant, controlling, et al, were thrown about, they would understandably be upset. IMHO, I can think of a number of qualities that would upset me far more than habitual tardiness. After all consideration goes both ways. One size does not fit all.
