Preface: My first job was in a knife store in Los Angeles when I was 15 and I kept with it until I was about 22 when the shop closed. The owner was an old veteran from Chicago. I basically had run of the place provided I didn't do anything inordinately stupid, or if I did, I cleaned up afterwards.
For anyone unfamiliar with Los Angeles, we have a lot of swap meets. I don't know why. But one of the largest is a once a month gig that surrounds the Rose Bowl stadium. It was a great venue for attracting weird customers using a reasonably steady supply of antique weapons the boss acquired through means I didn't ask about to maintain plausible deniability. The main doors had just opened so it had to be around 9 a.m. when this woman came up to look around.
Me: "Mornin', Howarya?"
Woman (pleasantly): "I'm wonderful! How are you?"
Me: "Doin' just fine. Anything I can help you find?"
Rarely do our customers have a specific item in mind, but are often looking for gift ideas or something, and sometimes they just want to look around because I've got weird stuff. This was a the latter. She looks around for a few minutes, occasionally asking a question without caring about the answer.
Woman: "Oh! What's that?"
I think she's pointing behind me, but all the merchandise on the tables between us.
Woman: "That! Your necklace!"
Me: "Oh, it's the hand guard from a Japanese sword."
Woman: "How much is that?"
Me (confused): "It's basically just a lump of iron. It came off my first sword, doesn't really have any value."
Woman: "Oh, is $30 okay then?"
Me: "Uh, no. It's not for sale."
Woman: "But I want it! You just said it wasn't worth anything!"
Me: "Monetarily no. But it's also irreplaceable. There really isn't a dollar amount you could offer me to part with it."
Woman: "Why are you showing off something you aren't going to sell?"
Me: "I'm wearing a shirt too but I ain't selling that."
Woman: "Hmph! A**hole."
And she storms away. My assistant for the day caught the end of the exchange.
Assistant: "What was that?"
Me: "I dunno but if comes back, kill it with something."
