A place where I used to work had the 阴盛阳衰 problem. I learned afterwards that one of the reasons why I was hired was to partially negate this problem, to slightly balance the gender ratio.
Many a time sometimes I have to go under the table to adjust the panawagon cpu everytime we change models. Some of those operators ( around late 20s and to mid 30s ) would purposely spread their legs and show they multi color underwares even thou they know I was under the table D-loading the software. I was in my earily 20s just came out to work and studying poly at nite.
