Our earlier post about "Shanghai's seven commandments" reminded Shanghaiist reader Ryan of a similar sign he saw when he was brave enough to enter a toilet stall at the Super Brand Mall's Lotus Supercenter. Hanging on the stall wall was another sign which we share with you below. Said Ryan:
"I had to screw up my courage and stand in there long enough to take the pics. The smell was vile."
Shanghaiist applauds Ryan's dedication.
