As a dude I try to shut down any customers saying sexist bullshit to my coworkers, but it still happens constantly. "Why isn't she cleaning that up?" Because cleaning is my job. "Shouldn't you help her lift that?" No, she's stronger than me by far. "Is it nice working with such pretty little girls?" Yes. Because they're excellent at their jobs, not because of how attractive they are. Stop being creeps! I'm gonna punch the next creepy man who hits on my underage coworkers!
