Seduce her

It's very clear that if things continue the way they're going now, you're not going to have a job after today. Now, that would hardly be the end of the world, but it's not something you want, either. You have bills to pay and you'd really rather avoid having to sell your underwear to weird dudes on the internet.

You take a long, hard look at Gemma. She always looks so stressed, with her graying hair and the deepening wrinkles on her face. But that doesn't mean she isn't sexy. You know for a fact she does hours of yoga every week in an attempt to make her more calm. Not that that ever works. But it means she's high-strung with a sexy body, and that's something you can work with.

You saunter up to the manager of the restaurant, an apologetic look on your face. "I'm sorry, Gemma," you say. "I really fucked up." But you know you'll make it better.

You're so close to Gemma now. You don't know if she's ever been with a woman, or if she's even attracted to them. But you know you're fucked if this doesn't work, and not in a good way. Besides, what's the worst that could happen? You're already going to get fired anyway. A tongue is a tongue, as far as you see it.
