Let’s get one thing straighten out for you. Guys think of girls like this all the time. It makes no difference if they work in a library with lots of clothes or if they work in a bar with less clothes. THIS IS WHAT WE DO!
Of course it’s going to be someone’s daughter or sister but that’s the way it is in life. They are not minors! That makes the whole difference.
About the flight attendants. They are not dressed like they are at Hooters. On the plane there are two service attendants with Hooters outfit. They are not flight attendants and are only there for the service part of the flight.
If the flight attendants had the same clothes, why wouldn't they gain authority?
You'll find that this is what makes men do what they're told. If a nice looking woman with revealing clothes ask them to.
