Shark Tank star Kevin O'Leary slammed office workers for spending money on takeout coffee and lunches. “Stop buying coffee for $5.50. You got to work and spend $15 on a sandwich – what are you, an idiot?,” O'Leary said in a video on his Instagram page. He urged workers to kick the habit and save thousands of dollars. “It costs 99 cents to make a sandwich at home and bring it with you,” he said. “You start to add that up every day, it's a ton of money. Most people, particularly working in metropolitan cities, are just starting on their job, making their first $60,000, [and they] piss away about $15,000 a year on stupid stuff, and that's what they should stop doing.”
