Bamboo Bistro in West Covina, California has signage posted on its walls that reads:
"Please avoid leftovers"
and, obviously the intended meaning,
"Pakiusap Iwasan Ang Pagtitira Ng Pagkain"
I think the management wants its patrons not to waste food, but isn't the use of "leftovers" improper in this context?
It's a pity my cell phone doesn't have a camera.
