Some trainers are VERY arrogant.
I had signed up for a multi day show and drove to the site to check out the stalls. I mapped out which stalls I wanted for my horse and then a tack stall.
I submitted my entry including stall choice. I arrived early to the show as a show team force of one - just me myself and I. I set up my tack stall and bedded my horses stall deeply.
In comes BNT who demands I switch my tack stall to my horses stall and visa versa because she wanted her stallion to have the end stall with no horse behind him.
I refused and said my gelding isn’t a fighter and things should be fine. They ended up being just fine but she was all sorts of nasty with me to get her way. I stood my ground not giving a fig about who she was or her stallion was.
That’s just the way some of them are and you have to assert yourself in their presence.
