I was out having a walk earlier today and I got a sudden very strong whiff of something like dog-poo. I continued on my way, but the smell did not go away. My initial reaction was then to check my shoes, in case I'd walked in any; nope. I returned back home and Googled for news that might explain it, keywords: 'broken sewer' etc. Nothing. By then I was really wondering if it was me, my imagination, or what

I was still puzzled when our cleaner arrived, so much so I risked embarrassment by asking her if she had smelled it too, and if so what was it'?
She became very animated and replied: 'Yes, I smell this too! When I came out of the MRT* I could smell it, very strong!'
I live in the geographic middle of the island. The MRT is roughly 1km from our building, and when I was out walking I must have been about additional 1km away vs the MRT. So it seems the issue impacted quite some radius.
Did anyone else notice this?
p.s. Probably disconnected, but who knows; the wind seems to have changed direction from last night, much of the smog appears to have been blown away.
