I feel you OP...
My husband and I are tea enthusiasts. The subject of tea came up at work yesterday and we were telling a coworker about our hobby. He was pretty clueless about it but was interested. At one point we started talking about oolong and I mentioned how I'd bought 100 grams of oolong for 32 Swiss francs ($34 US) as a treat.
This dude literally flipped out, like shitting bricks. I was like wtf? He seriously couldn't understand why someone would pay so much for tea. Even after we told him that it was rare and besides there are teas that cost way, WAY more, he just couldn't fathom it. We explained that to enthusiasts these kind of things have real worth, like collectors, etc. Dude must either be cheap as fuck or have no hobbies cause he was just sitting there laughing incredulously.
