Pessoas Estranhas

More hours of queuing in the notary today, hoping I won't get the lady with the moustache who rolls her eyes at me as she half-heartedly attends to me but listens conspiratorially to the other people at the counter.

I love the sign above the desk:

PARA UM BOM
FUNCIONAMENTO
DOS SERVIÇOS

NÃO É PERMITIDA A
ENTRADA A PESSOAS
ESTRANHAS

(For a good functioning of the services, the entrance of strange people is not permitted).

The meaning of the word "estranha" covers people who don't work/belong here, people who don't fit, and also strange in the English sense of the word. I wondered what the signification of the word was here!
