Quand on allume une cigarette

Quand on allume une cigarette sur un quai de métro ou en attendant un bus, il arrive //
When you light a cigarette on a subway platform or while waiting for a bus, it arrives

Today’s prompt is cigarette.

The quote above is supposedly one of the Murphy’s laws or maybe a corollary. Much shorter and helpful version is “If you want your bus to arrive, light a cigarette”.

BTW, the cat doesn’t smoke, he is just trying to conjure one of the municipal buses, or guaguas, of Las Palmas.
