Love This Sign!

OMG I love when i walk into restaurants and see stuff like this! lol The sign in a place I went to eat recently. I'm not going to lie and say it didn't take me a minute but then i realized duh, the restrooms are that way! lol

Is it tacky to want a sign like this in my house? Guests would ask and I would point to the sign. lol Have you seen a cool sign like this in a place of business?
