Huh. My boss Albert was on his way into the shop this morning when he noticed a woman at a stoplight with a coffee cup sitting on her car’s roof. He waved to get her attention and pointed at the cup. She called him over to thank him for the head’s-up… and gave him $15 in Starbucks gift cards. IT’S A PROMOTION. So if you see somebody driving around Sydney with a cup on their roof, let them know! Even if you don’t like their coffee, you can always give the cards to a homeless person.
