I finally stopped to visit "Grandpa Wally" today... didn't accept the oil change after all... I'd just had a bunch of work done on my car... but did talk to him about whether he needed a computer (he resisted mightily!) and whether he knew of any bargain cars for sale (he said he knew of a couple of retired ladies who were about to stop driving, so maybe I'll get a bonus from my visit).
He seems like a nice man... and I'll remember the business, and come back if I need car work in that area.
Thanks for the pleasure of walking in and asking for him... he wasn't surprised enough, but it was still a lot of fun!
Grandpa Wally has Mash, now... I presume he'll send it on to the owners, or something.
