chat_history: ["Man I can't believe I almost bought that thing at Walmart!", 'what did you almost buy?', 'It was a combination rice-cooker and vegetable steamer.  It looked so good in the ad, but when I got there, it looked cheap and shabby!', "It's hard to find good quality at walmart", 'I hope I can find one that lives up to the promise of that ad.  Maybe somwhere else, right?', 'I would try target.  good quality stuff there.', "I could try online, but I'd have to buy it first and then see if it's good quality."]
sys_response: try googling it, and read thru the reviews
situation: I saw something that looked really good in an ad, but when I went to the store to get it, it didn't look as good.
