I learned this from my dad... When I was young, we had a plumbing leak on a Sunday night, p-trap was leaking. All places were closed, so he went to a McDonald's bathroom and stole theirs to replace ours.
20 something years later, my faucet was leaking. It was a discontinued model from a brand owned by home Depot, though they still had the display model up. Remembering what my pa did, I took the display model apart and took what I needed.
The people at my gym! Half the dudes don't "believe" in deodorant, half the women smell like a perfume store.
Just yesterday, soon as I got on the treadmill, a young b.o. smelling dude got on my left, and an old lady smelling like perfume got on my right - I lasted 8 minutes before I couldn't take it and got off.
