If someone is willing to put in some time with chores and learning about ground handling(horsemanship) they are showing the ranch owner or trainer that they are more committed than just a lesson and then leave.

They are really extending their lesson by working around the ranch and are adding to their experience.

Some people JUST want to ride and go home.

Some don't even want to groom or even get the horse and want it presented to them all tacked and ready to ride.
The only time when I'd rather not have to be responsible for grooming/tacking myself is when the 50% white horse has found the lone mud puddle in his pasture, and is thus transformed into a uniformly brown yak. THEN I can see the lure of having my less-than-noble-steed all ready.

Honestly, the barn I worked at a couple years ago was my favorite situation: I came a couple hours before I wanted to ride, cleaned about 15-20 stalls, put all the indoor horses 'to bed' with their dinner then rode. Not only was I stronger physically, but it was a great excuse to hang out at the barn. We called it 'barn therapy', and I miss it!
Our current barn has a full contingent of staff being a busier place, alas.
