Around 1 p.m., right after the lunch rush, 87-year old Flo Silbach will start slowing down. She won’t quit, though. Oh no, no way she’s quitting. Her shift at Pamela’s Diner in Millvale doesn’t end until four. So, instead of shuffling around the tables and booths, jotting down orders in neat cursive and clearing empty plates once overflowing with hash browns, Belgian waffles piled high with strawberries, and BLT’s, she’ll just start her cleaning. Get all her chores done.
