Have you ever had a layover in Lagos? You'll love the tap water there!
When I turned the faucet on, it made a series of coughing and gasping noises, the faucet shuddered, then belched out dark yellow water with unidentified things floating in it.
That reminds me. The head chef at the crew hotel is American. I asked him what he was doing in Lagos and he told me he hated the US, and Lagos is a much better place to live. I'm a fairly open minded guy, but I struggled with that one.
