Okay, what part of "load the horses at 7" is ambiguous?
I calculate load time based on how hard some horses are to get into the trailer, distance we need to travel, the earliest horse to hit the show ring, lead time to dress horse and rider, plus a fudge factor to cover unplanned for issues.
Load at 7 does NOT mean arrive at the barn 6:55 and start feeding and turnout.
It's now 6:45, the client is nowhere to be seen and the 8 horses on this side of the barn are all staring at me with the "I'm starting, why are you not feeding me" face
