Fag trying to make a girl feel bad for being horny. That's what fat does to you. Stops you being sexual and apparently makes you care about your mcjob. I had a phase where i'd start fights over people wearing hats inside. It still disgusts me. Definitely worse manners than a girl filming herself masturbating in my proximity.
Ideally you're not fit you're sent to the all male farm, only around girls if you appreciate them. The more they want to be pleasured the better.
The smooth thing would have been to let her finish, say thanks for letting you watch, tell her you'd like to know how to rub girls, give her directions to your place, welcome anytime, welcome right now unless she wants to hang out here. You can be her escort, warn her wherever she wants to go.
Or close the place back in 15 minutes, ambush her, strip, do the same, move in hard for a kiss and put her hand on it. Tell her she's worth getting fired for but you'd like to take care of her, have her happiness your arrangement.
Back in 15 minutes carry her out the back, surprise her with no rape, make her comfortable, carry her home, hers or yours after your shifts over. If she's high, drugs or life help her stay high. Make it safe. Rescue her. When she's sober then do something serious.
