While
one's (such as, a street seller or a stranger) back is turned to you, you walk away quickly, so when
one's back is turned back around to return to you, they'
ll see that you're not there anymore.
A product seller at the Flamingo
Hotel and Casino had given me a
free iPhone 7/8 Screen Protector, he then was trying to sell me an iPhone Screen Protector for my iPhone X phone. He had turned his
back to me to walk over to retrieve the appropriate screen protector, which gave me the opportunity to ghost him.
