The world bank tells you half of the Chinese firms have emails but you won't know that far less than that of them ARE WILLING to use it. For taxing, they use super informal wechat group to send around notifications. I doubted if my tax officer remembers his email or has it at all. Regression adjustment or group it as outlier you know the best.

For hotels, I had experience that a 5-star hotel responded my message after almost a month. They have it but not in your way of using it.

Anyway, did you know the reason for their not writing that email?

Super agree. The designer of the experiment really need to read some books. And has him considered the situation that the “wallet” might be returned to the policed station?
