I went in to have the “check engine” light diagnostics done, and it turned out to be a repair that would cost at least $1,800. Alex did some research online (on his own, no request made) and recommended that I take my Tundra in to the Toyota dealership and see if it was something covered under the warranty. So I took his advice, and now Toyota is doing the repairs for $0! Alex very easily could have told me that he could do the work, and I wouldn’t have been any wiser. His recommendation cost him $1,800 at least, but it won him a customer for life! Thank you, Alex!
