Thanks Ricardo; interesting photos. Is it usual to see plastic on the floor under a table? Given the behaviour (eating) of the Asian folk at "the den" (Casino) in Brisbane, do you know if it is there in case of spilled or dropped food?
Plastic on the floor is unusual. In this case, the school had a calligraphy table set up for the kids to practice their ink flinging. Upon close inspection, the bottle of ink and some brushes can be seen. The writing was all done on napkins while using paper plates as wells. With wisdom, they placed plastic all around to protect the auditorium floor.
