Just my 2 cents, but over the years I’ve worked for 5 dealers (3 Subaru), briefly for an independent, and ran my own shop.
In none of those operations did I ever treat or see a woman treated differently than a man.
What I HAVE seen a number of times is women being offended because they think they’re being picked on.
Car comes in with problem. Problem gets fixed. Car goes out the door no matter with no regard as to whether the owner is male, female, 50/50, or some species of alien. Money is green no matter who hands it over.
I’m not saying there are no sexist people out there; only that they are in a distinct minority and it’s very unfair to tarnish the MALE mechanics out there with a one size fits all shoe.
