Being Catholic, and going to St. Anthony's school, every Friday we went to Mass and Communion so that meant no breakfast until after. Donuts came from Spudnuts on Federal Hwy, and maple nut rolls from Stevens Bakery downtown by the RR tracks, and they were worth the wait!
I started working in a Serbian bakery in Chicago in 1965, on Saturdays and Sunday mornings. The bakery was just down the street from the Catholic church. They had 5 Masses on Sunday and after each one we were flooded with customers, like 4 or 5 deep in a row at the counter, no taking numbers back then either. There were 4 of us working the counter and when each crowd cleared out we were all wiped.
