Sit down next to someone and start a conversation with them... Except don't tell them the truth about anything. Make up total lies about yourself and your life. You could tell them that you are a billionaire or that you are a celebrity. Be creative! And see how crazy your story can get with the stranger still believing you.
Go VIP shopping
Go into stores like Pandora and Michael Kors and pretend that you are rich. Tell the shop assistant that you have a maximum spending budget of $1,000 in their store. It's incredible to see the treatment you receive when they think you're loaded with dough.
Then, when you're done having fun, just say that you'll come back to purchase the items because you need to grab your wallet. (But don't!)
Look the eatery menus
You see, this one is the most entertaining because just the prices will make you burst out laughing. You might cry a little too.
Examine security techniques
Sit nearby to the security gateways and watch the techniques of the security teams. Note what kinds of people are pulled over for further examination. You might learn some ways you can avoid getting the time-consuming explosives test in the future.
Look for change
Wander the terminals with your eyes focused on the ground searching for dropped coins. If you find enough, you'll be able to unlock one of the Smarte Cartes. Then you can try to surf it until airport staff get grumbly at you.
Art and craft
Take some straws, napkins, sugar sachets, and whatever else you can find, and build something out of it all. Maybe you can make a plastic straw hat or a napkin dress. Then you can attempt to sell it to airport dwellers.
Log into the free wifi
Join the Sydney Airport free wifi connection and read articles like this that probably won't give you any realistic ideas, but will waste a minute or two while you read them.
Amelia Warrandyte _ Having just read your article where you suggest Lying to an unknown deliberately for mere entertainment. This site is targeting family types along with older (farts) like myself. There are some folk who may never see through the charade. I see little profit in an activity of such merit. The remaining article and your other contributions are fine and thankyou for such.
