Everyone always bends over backwards to explain why it is apparently so much more expensive to have the same exact grooms grooming the same exact horses at the show instead of at home, but apparently it all evens out.
Since it doesn't actually cost you any more, why charge day care?
I have always balked at the idea of paying a $75 day care fee when the horse is already paying full board at his (empty) home stall and the SAME GROOM is getting paid the SAME to provide the horse with the SAME services he would have received at home. Good to know the groom sees none of that money.
As for my situation, my small program does not usually have any grooms (other than me and the horses' owners).
Therefore, if a groom were to be hired for a show, it would not be someone who would already be getting paid regardless -it would be someone specifically hired to do extra work that one person can not do alone in the tighter time frame of several horses doing the same division as opposed to being ridden/coached throughout the week.
