Many, many, many . . . way too many . . . years ago when a teenager, my buddies and I were privileged to use the back half of a large shop for our automotive shenanigans. The place belonged to my best friend's father and it served his heating/air conditioning business during the day but our 'speed shop' at night.
Best thing was . . . it was a half-block from the local Wonder Bread bakery. When we were working in 'the shop' in the middle of the night, those guys at the huge bakery would be cranking out fresh bread in copious quantities. That aroma permeated the neighborhood and drove us crazy. Eventually we discovered the 'back door' and some amused but kindly night shift guys flipped us each a hot loaf.
Wow. Even without butter that was outstanding melt-in-your mouth snacking! To this day, the combined aromas of degreaser, fresh motor oil and hot, fresh bread conjure up some great memories!
