(picture of door) Ever wonder why doors are made out of glass? This picture gives a hint. Imagine that these restaurant doors are both closed and someone tries to leave in a hurry just as someone else tries to enter the restaurant from the outside.

The doors are made of solid wood and are beautiful to look at but you can't see if anyone is standing on the other side.

(picture of door sign) Here is a close-up picture of the sign posted on the inside of the door... This sign was probably motivated by someone getting whacked by the door being opened.

Design suggestion

Make sure your design provides displays of everything a person needs to see.
