I think a lot of men (& people in general) have the "It never hurts to ask" mentality. Which may be true in some situations but in this hobby I can 100% see how it can be offensive/disrespectful.
Another insight (not an excuse for bad behavior) is the mentality "people will do anything for money". Which is shitty outlook on the world around you.
You can never ever buy respect, it's earned.
It also should be a common courtesy to respect everyone until their actions make you loose respect.
Courtesy and manners go a long way in life.
