i am glad you caught it before anything really happened, but i honestly dont think you have any course action laid ahead of you, i think you might just have to grin and bear it, find out what days mr weaver does not work and have your oil changed then, or start changing yourself......
or, you could continue to go to tire kingdom, dont say anything about, and if he really did it, bait him and try to catch him following through with something he was already planning....
