Lousy customer service, overpriced china sweatshop junk, cheating customers at the register, a sickly dirty looking produce department carrying every disease that is making people sick and even killing some, gift cards that never work, etc. are a few reasons that come to mind. By the looks of mao's employees and clientele the stores are probably crawling with bed bugs and even worse.
I wonder if he spoke English or is unfamiliar with mao's $25 theft limit policy... I'm waiting for obama to initiate a doj investigation alleging the foreigner's civil rights were violated because no one explained the policy to him. I also noticed a few clerks outside leaning on cars smoking cigarettes that they can now afford due to their pay increase. Some things never change and mao's appeal to dumb low lives is one of them.
