Question to the mechanics out there

So, I'm stumbling through my first complete build. I knew I didn't have all the tools, and expected to stop in my LBS for some help. All my parts come in, I head over and ask for help pressing my headset into the frame. Also, I asked if they would show me how they did it.

The nice guy whom I've spoke with before went back and asked one of the mechanics. I over heard him saying "no one likes to be watched" as part of his response. The nice guy comes back, tells me that they aren't a fan of being watched and that it would be Tuesday or Wednesday before they could get to it.

Normally this wouldn't bother me so much. I don't expect to walk and in and have my bike in a stand that minute. In this case, out of the 3 mechanics working, 1 had a bike on the stand, the other one whom the sales guy talked to was sitting there with his legs crossed, with the third mechanic so bored that he was sitting next to his empty stand popping bubble wrap, one by one. This is what bothered me.

Now to my question.
Mechanics of Reddit, does it bother you to have someone ask to watch or have what you are doing explained to them? Assuming you aren't swamped with bikes for other customers. That I can totally understand, if it is really busy and you have a ton of work to get through in a short amount of time. Yeah, you don't need a newbie like me breathing down your neck while you try to work. At the same time you can't tell me that every bike mechanic learned how to repair bikes by themselves through books and youtube. Without any of my LBS offering repair classes, how do I go about this?

Background on me. I coach college track and field. I use the mentality that Boo Schexnayder, a extremely intelligent and successful coach once shared with me. He taught a class I attended and at the end said that he didn't get where he was without a lot of help from other people that were more knowledgeable. He went on to say that it was his duty to do the same thing for those people who wanted to learn, and encouraged us to do the same.

The sales guy did give me the name of a mechanic who would help me out, while the other guy wasn't around. At first I was going to be stubborn and spend a small fortune on tools that I will use less than a dozen times and do it myself learning the hard way.

tl;dr small rant, serious question
