sign at City Gate in Port-of-Spain is intended to encourage
people from throwing their chewing gum on the ground or
sticking it on seats and other thoughtless places. Appears,
however, that gum-chewers do not take kindly to instructions,
so they are sticking their gum on the sign. Maybe the sign
should be changed to Please stick chewing gum on wall.
But keep the bin in place, just in case.
