Service Dogs?

We went to Hollywood ... the one in Florida with the Circle Park and the little stores we can't go in, not the one where they make the movies ... and there were some people out with these puppies.  There were two goldies, a golden lab, a border collie and an australian shepard and they all had little jackets on that said "service puppy in training".  They said there were from South East Guide Dogs and they were getting the puppies used to being around crowds and going into stores and stuff.

Anyway, they saw us and wanted to play and we wanted to play with them, but we weren't allowed because they were "in training" and they can't do that when their real guide dogs.

But I was wondering, do guide dogs/service dogs get to do fun things too, or are they always working?  I mean, I know there are times when we have to behave, like when I'm in harness I can't goof off, but we get a lot of goof off time too.  So do service dogs get goof off time or are they always working.

We went to a baseball game once and all the doggies were getting treats and everything and hot dogs and there was a service dog, but my mom had to ask if she could give him a treat and he didn't get any hot dogs at all, and that just seemed kind of sad.

I hope they get to play too, and that they just aren't working all of the time.
