Yes, I was told yesterday that I should charge! I don't mind doing stuff if it's needed and going to be acknowledged! But even I thought they were taking the mick!
I'm a yard owner and we always bring in if there's an emergency, or for other reasons depending on circumstance! Yesterday I brought in 2 horses that had been left 24/7 out by the owner in thin rugs in cold rain and who'd overslept and couldn't get up to feed them! I also fed them on my own hay...
