[Blink]

Saw this work today, it's the dumbest thing I've ever seen , but I might as well share it with you guys. This sounds stupid, and that's because it is. But I've seen it work. Only use this on really dumb people, if the person at the desk doesn't seem dumb, wait until someone else takes over.

Spoiler: Method

Step 1.

• Find the discount you want
  

Step 2.

• Version A:
  
• Print out the page with the discount or print a screenshot.
  
  Version B:
  
• Print out a random barcode or coupon-number
  

Step 3.

• Give it to the desk-person
  

This should work in massage parlors (where I saw it done).
