Istanbul

On the shores of the Bosphorus, they once built a city beyond reproach.

Now the successors of Suleymān the Magnificent clamour for EU membership, and on their trams they put up warning posters such as these.

I thought it was a warning against wearing scary masks on public transport (or perhaps a reminder that what seems like a devil with horns on the 9.45 to Zeytinburnu may in fact be a chubby businessman with a juvenile sense of humour). But apparently the sign says Please give priority to passengers who are alighting.
