That's what I was thinking

Perhaps the cashier knows OP personally? Or maybe OP is a regular customer and thus the two have become somewhat familiar with one another. Either of those situations might also explain why the cashier felt at liberty to be so sassy with a customer.

My guess was that the cashier was into women and was speaking from experience, or that the world is finally leaving heteronormativity behind

That's not what's being discussed....

My thoughts exactly

@16 the gender identifier for the post says female

On my app it doesn't have the OP's gender. Just the username.

Yeaah, I really wish the app would show gender and location once again. Even if not in situation like this, we are missing a lot of info.

OP could have been dressed as what people look at as the stereotypical lesbian. Or OP could have been wearing a shirt that says "I LIKE VAGINA."

Honesty is no excuse for being rude.

Some people breathe really hard which presses the scent of your breath towards them. I babysat a kid who was a mouth breather and you could smell his breath from 2 feet away. It wasn't necessarily bad, but you could smell it.

You're allowed to write the word "Fuck" here at "Fuck My Life." Just FYI.

Calm down. :)
