chat_history: ["I always buy the same brand of yogurt and don't even bother trying other kinds. It's just so delicious and such a good price that I'm a loyal customer for life", "There's very few brands I feel that strongly about. What kind of yogurt is it, I might want to try it?", "Astro balkan plain! It's not as pastey as greek yogurt, or runny like other kinds"]
sys_response: I don't think I have ever seen that kind in the store, I'll have to look for it next time I go. I don't care much for the runny yogurt, but I like greek yogurt so long as it's whole fat and sweet.
