Do Not Leave Your Baggage

I saw this reminder last night posted on a wall at Maria De Leon Bus Station in Manila near UST. I think "baggage" is a collective noun so there is no need to add "s" to pluralize it. Anyway, more important for us travelers is to heed what it is trying to tell us!

A Tagalog version (below) of the same reminder is also posted, though it is not a direct translation - it says more! Mag-ingat na lang lagi!
