My biggest pet peeve in the world is being late, and people who are late to a time you BOTH agreed on >8| And then when they're not in the saddle, ready to go when you get there.
What if I had other clients? I don't yet, but I am planning on starting up lessons for realz this summer, at which point, if you're not ready within 10 minutes that I step foot on the property, you're S-O-L.
When I do lessons, I take 30 minutes to brush my horse down, tack him up and warm him up - I was always prepared!!! Which is why I may have gained more knowledge from the instructors, but really. Being on time? Ain't that hard. EVERYONE has a clock! It's so rude and inconsiderate, and it just drives me insane!
