I’ve been designing signs for over 20 years, and every few months I have to repeat this scenario with a client:
Client: I need the sign to be double sided with an arrow pointing to the right.
Me: You need the arrow pointing to the right on both sides?
Me: You realize that if the arrow points to the right on both sides, coming from one direction, the arrow will point your target customer in the opposite direction from your location… right?
Client: No, we’re on the right.
Me: I know you’re on the right coming from this direction, but coming from the other direction the arrow needs to point to the left.
Client: No, we’re always on the right.
