Jugaad engineering isn’t always a good or safe thing. I had to spend a couple of hours at a government office recently. There was a water cooler, with a single glass, and no glass holder. Some bright spark had decided to use the loops of the wire powering the water cooler for the glass, which seems pretty clever, until you realise that the wire is connected to a plugged-in socket and that the glass is metal.
I attended a small but interesting book-club meetup at a CCD last weekend. After being asked three times very nicely, the server deigned to bring me a glass of water. He then came back five minutes later, asking me if I was one with the water, because someone else wanted water and that was apparently the only water-glass in the coffee shop.
