Have the exact same set up in 3 of my MIL's 4 apartments. We repaint the steel cabinets with every new tenant. Just replaced the sink strainer on one.
My daughter on a business trip heard this rhythmic thumping coming from the next room in the hotel. “Uh huh, I know what they’re doing. “. 5 minutes later and it’s still going on. “Hmmm… impressive!” 20 minutes later it’s STILL going on. “My God can’t he get his rocks off yet?!?!” Finally it stops.
