I've seen many variations of this sign, but never with actual illustrations, intended, no doubt, for the shirtless and shoeless illiterate. Though, it is odd that this sign appears way in the back of the restaurant. By the time you notice the sign it might already be too late.
The "no" symbol of the shirtless man could mean so many different things, couldn't it? Scott's Dairy Freeze, 234 E North Bend Way, North Bend, WA.
