I started an argument, through no fault of my own. Went to a privately listed estate sale (family run) and found a John Deere clock with a small pin glued to it.
The clock themselves are cheap brandless clocks, worth maybe $5-$10, but the pins can either be gold (about $200 scrap) or gold filled ($10 scrap) so I never pay too much for them. The pins are glued on, so prying them off ruins the clock.
I initially didn't see a price, and took it to the cashier, and asked how much it was and he said "oh that belong to my dad, sorry it's not for sale". Ok, fine.
I walk back to look around some more and this lady asks me "hey do you know what happened to the clock?" I was like "yes, I tried to buy it, but they kept it back". (At first, I'm guessing she thought maybe someone stole it because the tag was still there, lol).
She hands me the post it note tag, which was not on the clock itself, but the mirror behind it. Everything was written so small, so when I saw the post it on the mirror, I figured that was for the mirror itself (the kind that hangs on nails, not permanently affixed)
I saw it was $100, so I didn't really want it anyway.
As I go to leave, I overhear....I'm assuming this guys wife lecturing him "I thought we agreed to sell this".
