Other professors used to take me to snacks when I was single, so I was well aware that hostesses were mostly divorced or single mothers. Mimi sheds light on the nature of snacks by saying that #Japan has a dark side. Regarding the #social#inequality that Greg mentions, Mimi clarifies that there is a double standard whereby men can go to snacks openly, but it is shameful for #women to work in them. Now I'm a family man, but I sympathize with such women, who would otherwise have to #work for close to the minimum wage.
