A Great Trick
The next time you enter a restaurant, choose a random stranger of your preference.
When you catch their eye, maintain eye contact for a while, look away, and act like nothing happened.
After a while, do so again, this time keeping contact for a longer period.
The stranger will most likely start paying more attention to you, but act normally.
Keep this up for a while, before walking up to them.
Greet, and ask them to close their eyes and picture a playing card.
Now, when they are doing this, eat as much of their food as you can and run away.
People are weirdly willing to obey instructions when they think it’s for a magic trick! :)
