Yeah but I don't see how a lecture about different types of bikes gets you to finding out what size tires a person has on their bike. It's certainly not a direct way of doing it.

Anyway, if I'm understanding this right, the bike needed some adjusting before the tune up but after the tune up it's making new noises at times when it should not be making noises, and the answer from the shop was that it's supposed to be that way. That's just wrong.
