The Philosophers

 
Dear Readers,

The following real-life conversation was recently observed online:

Melanie:
Is wondering why they have Braille on the key panel of drive-through ATM machines...
... yada yada yada

Coraline: 
I have thought about that very same thing! Go figure!!!
... yada yada yada
Peggy Sue:
I have often pondered this myself.  Have you ever touched the bumps? I did, just to see how they felt, and wondered what they meant. Now, what is written in Braille on the key panel?

Now, what is written in Braille on the key panel?

What an intriguing question!  Burning for an answer, The Editor made a beeline for the nearest drive-through.  After extensive investigation, using the Braille under number 6 on the numeric keypad as a test vehicle, four distinct possibilities emerged as to the precise meaning of the puzzling bumps:

1. Beef with Broccoli 芥兰牛肉 
    ... although this might very well be translated as:
2. Happy Family 幸福家庭 
    ... since the middle bumps seemed a bit worn
3. You're not blind!  Why are you pushing me?
....Help Security...
  
 ... strangely enough, the final possibility is...
 4. the number 6

Research continues as the truth is out there somewhere...
