When i take my car to dealers i always wait for my car. I also walk about around (not in) the garage. I have seen some shady things. The first time a friend dropped of a car for a tune up it didnt run right so i double checked all the work and they never replaced half the parts they said they did. i trust very few with my car or bike.
Since we slab to huber so often that part doest bother me. It was worth the ride there to ride on those roads. Now more than ever i want to do a track day.
