I am an old crab these days...if I don't have green in my hand, it is not sold...I don't clean up, bathe, vaccinate, or get out of my chair until I am paid...I have wasted too much time on no shows and so forth...I come from an era of information...if I have a change of plans, I will call you so you don't waste your day waiting on me...if I can not do something or afford to do something, I will tell you...if I am going to be late, I will call you...I think it comes under the heading of common sense and courtesy...some people have neither one of those in their kit bag...they are I and me oriented...and everyone should take a chill pill and not mention it...not in my world!
