...two things. (At least today.)
First, it turns out, if you don't get into the Tube in time, you wind up either having to walk several miles in the rain or you have to catch a cab in the City and spend £23 getting back to your hotel. There is no other OECD capital—I mean, none—that fails to provide 24-hour public transportation. Except Washington. But let's not discuss that for a moment.
Second, what the hell is this?
Before you say, "duh! It's a sink!", let me assure you I was able to identify the fixture in real time when it became relevant to do so. What I cannot fathom, so to speak, is how the United Kingdom has enjoyed 2,000 years of indoor plumbing and yet cannot seem to construct a washbasin, shower, or toilet that handles the basic necessities of the task for which it was constructed.
Take this thing. Those tiles are the same as U.S. tiles, about 13 cm on a side. The sink, therefore, is about 20 cm across and 15 cm deep, meaning unless you have hands smaller than the average park squirrel, they won't fit in there. Also notice, despite the technological advances made since the second century of the common era, there is a hot spigot and a cold one. On average, the two produce water at a comfortably warm temperature. Separately, one produces water barely able to remain liquid without flashing into superheated steam, and the other produces almost-freezing slush.
Can someone explain why these ridiculous dual-faucet sinks have survived into the era of the printing press and the wheel? It just doesn't seem like a great intellectual leap to prevent freezing and burning when trying to wash one's hands.
