@Meup: I think what people say on the internet is usually more strongly worded than they would ever do in person. So that is what I meant by taking posts into context. At times it seems like there is a COTH mob ready to storm out with pitchforks and torches. But in real life I don’t think people would really act like that, unless we are talking about Hillary vs. Trump.
Back to the main topic: whatever happened to people starting a new job and trying to get a feel for the place first before “peeing” on what they think is their new territory? Copping an attitude and yelling is not the way to win friends and influence people.
If I would have been new employee, this is what I would have done. Well, first I would have made sure I understood the rules at the facility at which I was employed. If the person, i.e. OP, seemed to be breaking a rule the most I might do is walk over to them while mounted and say “I believe according to the barn rules, horses cannot be handwalked in the arena while other horses are being ridden”. That way the issue is the rule, not the person themself.
If there was no rule about handwalking, then I would do nothing. If I felt it was a big problem, I’d ask the BO/BM about it since it is their barn, their rules/MO, etc.
I certainly would not yell for any reason, unless someone was doing something that could cause serious and imminent harm.
