My hands are dirty in a Cambodian restaurant

I'm at a talent show with my brother. A guy is doing a very abstract version of "Stairway to Heaven" accompanying himself on organ. When he gets to the "and as we wind on down the road" part he gets up from the organ, walks across the stage, picks up a folding chair which he uses like cymbals.

When the next performer gets on, I tell my brother I've seen him before and it will be really good. The guy intentionally sings out of tune and is intentionally horrible. The judges gong him off stage and I realize the whole thing is a planned production.

We're outside the theater and I need to wash my hands - there's sticky crumbs all over them. We enter a Cambodian restaurant - I don't immediately see a bathroom. I wander through the dining area dipping my fingers in bowls of water on the unoccupied tables. I'm not sure if the bowls are for washing or eating so try to do it without anyone noticing.

I find a bathroom near the entrance. There's an odd urinal type thing that has a second toilet one could only reach if you climbed down through the first urinal. A sign reads, "There are TWO toilets. Please don't use the first one when the one below it is occupied." I wash my hands.

Outside the bathroom is a small standing bar. My brother explains that Cambodians always each standing up, so if you want an authentic experience, you'd have to stand at the bar. I look at the menu which has the Cambodian names for the dishes in phonetic English. The menu doesn't say what's in the dishes, the descriptions just praise how good it is, say what city is known for the dish, etc. I make a mental note to try eating there sometime with someone who knows Cambodian food well.
