What did the confused tourist say when he exchanged currency for an unknown exchange rate while visiting Seoul?
“I have won, but at what cost?”

I saw this in an elevator in Emeryville CA in a new building that was built this past year. I don't know if that makes a difference. The elevator has a pair of buttons that seem to indicate "open door" and another pair that seem to indicate "close door", but the pair on the left have a vertical bar between the arrows, and the pair on the right do not.
I've pushed the buttons, and maybe I'm not astute enough to notice some subtle difference in function, but as far as I can tell, they just open and close the elevator doors.
What is the vertical bar between the arrows supposed to indicate? Is one supposed to close the door harder or more emphatically?

Just wrapped Day Zero Festival 2026 in Bali. Thought this community might appreciate the numbers.
The setup: 60 dry-composting wooden toilets. No plumbing. No chemicals. No water connection whatsoever. Just the toilet, local Balinese sawdust (0.5 kg added after each use), and a sealed container underneath.
What came out the other side:
- 36,000 total uses across the festival
- 18,000 kg of compost produced
- 0 litres of water used (standard flush would have used 216,000–360,000 litres for the same number of uses)
- ~27 tonnes CO2e avoided vs. chemical toilets — equivalent to about 1,240 mature trees working for a year
The compost goes straight to our flower farm. The flowers grown from it get gifted back to festival guests at the next event. The loop closes completely.
Sawdust sourced from local Balinese woodworking workshops — material that would otherwise be discarded.
I'm the founder of the company (Ecoranah, based in Bali) so obviously I'm biased — but happy to answer any questions about the system, the composting process, how we handle pathogens, logistics, anything.
