Too much to ask

I am at a clinic over the next couple days and I always want it to be different and it never is, there's always someone who makes these things unbearable.  By unbearable, I mean slows the whole clinic down with stories and repeated questions that are either not relevant, or have already been answered.  I am not saying that questions should not be asked, but I wish some people had a better sense of what can be answered immediately and what might wait till a break, or even a follow up email.

I remember waaaay back in college we used to make fun of the non-traditional students (i.e. old people) and the way they always asked multiple questions and slowed class down.  Now that I fit in that category, I am aware that I am not as sharp in some aspects as the younger folk, and also that I am not going to be the one to cause them to tune out.  I saw it today, about half the class zoning out and almost becoming unruly due to the instructor answering a question a 3rd time.  

That being said, this training looks like it will be extremely informative and I am glad to already have taken away some good techniques and helpful hints.  This is reassuring as I have another 1 & 1/2 days to try to deal civilly with annoying people.  I really don't think it is too much to ask for people to be aware of their surroundings.  On second thought, I better wait to ask that question when it doesn't impinge on other's time.
