Just Ask
First full day in NYC. No matter how often you visit this city, it continues to amaze you. If you want to experience 'fast', come to NY. Things keep changing and if you're not keeping up, you are gone. The thing that doesn't change is the art of selling.
Everything is sales. People are not afraid to ask for a deal, an upsell (also known as an upgrade ;-)) or just your money. My son figured it out really quick: "Dad, at home, we're just too friendly." Case closed.
