A washroom with Da Vinci Code

I went across a newly renovated hawker center and saw this sign yesterday.

Which side for man; which side for woman?

To solve the puzzle, you got to have some basic knowledge of symbolism, or to see the Da Vinci Code movie/book.

The fad of Da Vinci Code has left its mark in front of this toilet.

Singaporean really have a sense of humour here, though it is a bit stressful for those running around to answer the nature call.

I wonder if a person sees a star of david outside a washroom, what should s/he do?

My advice is,

Do your research before do your business!
