Saying "I watched him send it" is like saying "I watched him paint my portrait".
Sure, you sat there for the portrait.
Sure, he looked at you, dipped his brush in the colours on his palette, and placed some strokes on the canvas.
But did you actually SEE what he painted?
Especially odd if your artist was Dali, Escher, or Picasso.
Sure, you sat there facing him while he tapped his fingers on some keys on the computer.
But did you actually SEE what he typed?
Did you watch him select MY pharmacy?
Did you actually SEE the confirmation on the screen?
He could have been making lineup changes to his fantasy teams, moving the money from your visit into his "new car fund", or making dinner reservations.
Especially odd if you see Dr. Acula or Dr. Lechter.
"We only see what we want to see."
