Now that you are a "regular customer" and they clearly remember you from one time to the next, they know what they recommended last time and they know you declined. When he asked you "Last time you were here, we recommended you take care of some things, such as the brakes, are you interested in taking care of that today?" he was offering you a courtesy check. When you said "No, thanks," if I had been him, I would have believed you declined. You pretty much told him you wouldn't consider fixing anything so he shouldn't bother. Why would I walk you through a list of things that needed to be done when you had told me up front "No, thanks." My suggestion, instead of "No, thanks," would be "I don't really remember what all was recommended..." or "I'm not sure, the brakes and what else?" or something other than "No."
If you explained in your report, you probably don't need to be worried, because he actually broached the courtesy check with you by mentioning the brakes and referencing the last time you were in. I think he met the requirement for going through the courtesy check. Next time I would just be more open and let him go through it instead of shutting him down so soon.
