The hotel has sour taste.

Hello, I do cooking and catering. I have traveled all over the country and have never seen sour tofu. There can be stinky tofu, fermented bean curd and frozen tofu, but there is no acid. Obviously, the clerk is lying for fear that you won't pay. As for diarrhea, it's hard to say. It depends on your immunity and resistance, and how much you eat. Eating too much, no matter how good your body is, can also lead to food poisoning.

If we don't solve the problem on the spot this time, we must protect the rights and interests of consumers next time. If the problem is solved on the spot, forget it. If not, you can call the epidemic prevention station or the news hotline to solve the problem.
