There is a family that rides at my barn who has this same complex. It's a high end barn, but tack up etc is usually not included, but they have 4 horses there including one that is for sale for $225,000, so they get treated differently than the rest of us. Lol.
There is a panic when the barn gets a call that they are on their way and the grooms rush to get their horses ready. If they show up without notice and have to tack up their own horses, the rest of us just sit back and chuckle at their efforts. (yes, we stop chuckling and help them, eventually) The younger girl can't put a bridle on and doesn't know how to work a girth. Seriously? There aren't too many parts to a girth!!
I just feel bad for them. They don't really seem to have a close relationship with their horses. They hardly pet them or talk to them when they are working with them at all. I carry on full conversations with my horse.
Franknbeans is right, it's the "horsey experience" and it's what makes it all as wonderful as it is. (IMHO)
