That's it really. I have signs up explaining that one has a medical condition and that treats such and carrots, polos and apples could kill. But it's the holidays and families are walking past more often and just can't ignore it. Even grabbing a bit of greenery and offering it over the fence... it could be a poisonous plant. The thing is, my horses love a bit of a fuss, there is no need to wave the remains of your sarnies about to get to meet them. It's no different to offering food over a garden fence to a dog, but people just don't see it in the same way. If I didn't have the signs I could kind of understand it.
I'm not running a fucking petting zoo.
