She deadpans and glares. “Seriously? But I work there! What kind of date is that?”
“Uh...” You frown.
“Wait a minute—this is just a ploy for some free food, isn't it?” She snorts and tosses the rock in the fountain. “Well you can forget it! The Cakes complain that I give away too much free food as it is. I can't bring home a freeloader as well! Sorry, but I'm on to you, bub. Now if you'll excuse me, I'm going to find some ponies who actually appreciate me.” With that, she grabs her bubble solution and walks off.
You almost had her too, but you went and suggested something dumb. Better luck next time.
