Yeah, I saw it. He's not paying a substandard wage. He's paying a higher end wage for his industry. And other people aren't footing the bill. That's a misunderstanding of the restaurant model of today.
Legally, the wage for food service workers is only $2.83 (roundabouts) and wait staff is required to make up the difference in tips. If the tips fall short then the restaurant is supposed to cover the shortfall. So, if a restaurant is paying the staff $10/hr before tips and letting the staff keep their tips instead of applying those tips to the wage then that's a pretty good place to work for waitstaff. The take home wage is actually more than $10.
Compare that with a restuarant that pays $10/hr using the normal model. The staff would have to apply their tips to their wage and then the owner would only pay enough to get them to $10. Which might mean that the restaurant only pays $5/hr and the tips cover the rest.
The business model is very different for wait staff. Believe it or not, Kong is treating his staff pretty good.
