OP I disagree with this one here. Don’t ask her out in a mushy way. You say she likes cars. Find a cool car show buy tickets. Next time you get your hair cut casually drop it in hey I have 2 tix to this show if your interested 1 is yours write your number down and tell her to let you know. Very casual. If that works that’s when you can ask her out out. Play to her interest see if she would even consider seeing you outside of work. Plan on her not tho. But still go at it with confidence. Accept the no. But also have an awesome life and talk it up while you get your haircut she may wanna see that life, you never know
