Props to you instructors.

LOL! Yes, it was a rant, but the whole point is that once you've ranted, you need to let it go for good, otherwise a change needs to be made.

But they aren't 'good' clients. Or they'd have called you to say they're running late, rescheduled, or whatever. A good client doesn't run late regularly. A good client might be late once in a blue moon and for those, you don't ever feel put out or having wasted your time. Those once in a blue moon late clients pay you extra for having to wait for them. They buy you an 'I'm sorry present'. They offer to take you for dinner. Etc...

Repeated lateness is a blatant act of disrespect. They're more important than you. That it irritates you is a sign that at least subconsciously you know that and it doesn't make you feel good.

Okay, getting out of my psychologist's chair now.

Haha- I like the idea of taking tack away :). It drives me CRAZY when people are late for lessons, especially group lessons, because if it's a problem that my instructor needs to work out like tack, injury, etc., we ALL are wasting our valuable time sitting in the arena adjusting our stirrups for the tenth time for lack of better things to do. I always make sure I arrive at least 45 minutes early for my lesson; that way, if I have trouble bringing a horse in from the pasture of if they have some little cut that needs taking care of, I won't be wasting anyone's time and money.
