Most of the girls at the Korean shops...
are fat and out of shape.
Seriously I went to Juliets in Burwood and there was like 10 girls in the lineup, all out of shape. I walked, can't believe I walked from a lineup of 10 girls! Pretty much the same observations at Midas.
One thing unique about these Korean shops is they have party rooms, where guys come in groups and drink and socialise with the girls, they also stay open till like 6am! So these girls are drinking alcohol all shift and staying up till sunrise. There is zero chance of staying in shape doing this. Even if you meet a girl in great shape, in about 6 months to a year of her doing this gig she will have lost the weight battle and you can't really blame her.
