Walked into a Panera Bread restaurant today with my people. While navigating to the counter, I found a table with an iPad for ordering. Below the device was a sign in Braille, that I came upon completely by accident! It said: "Welcome! To launch VoiceOver, (headphones at register), insert headphones into jack and double-tap screen with 3 fingers". There's not enough Braille signage in the world, so this one was certainly, a "welcome" discovery!
