I read this post on another young expat’s blog, and I had to send a link to it. Basically, two-tap sinks are, inexplicably, extraordinarily common here. I think it’s because people don’t like change. Not only that, but you can’t turn off the water supply under the sink without an Allen key! How ridiculous! I’d note that the writer didn’t know that American sinks allow you to turn off the supply with knobs, but I left a comment to allow her to continue loathing them unconditionally :)
