Greif's Cafe
The moment Greif handed her the tea, Spin quickly scurried off to clean the already-clean tables so she wouldn't have to witness the results.
Greif, however, simply leaned against the bar the whole time, arms folded, smirking smugly. He took pride in his work, and loved it when customers enjoyed their service.
Once she's done and makes her remark, the griffin grins. "Well, in that case, I'll make sure to promptly prepare a blueberry scone and some blueberry tea every time a particular pretty purple pony trots into my cafe," he cheerfully replies. Yay for flirty alliteration!
