Look, I Get VERY Thirsty, Okay?!

I am the idiot customer in this story. I’m in a sporting goods store to buy a new camping bottle, having lost the old one. I find one that’s a bit too small, so I ask the saleswoman:

Me: “This is 0.5 metres; it’s too small. I would prefer a 1.5 metre bottle.”

Saleswoman: “Metre?”

Me: “Well, it was written 0.5 on my old bottle, anyway.”

Saleswoman: “But are you sure that it was not in litres?”

Yes, it was in litres. That poor saleswoman was imagining a 1.5-metre water bottle!
