Why would AWS be any different?
The way to hell is paved with well intended analogies.
I certainly feel less responsible and more aggrieved when that situation costs me a lot of money than in the $200 wine example.
Amazon is thinking about customer retention and growth, and about the goodwill lost in refusing such a request. The restaurant is thinking about the likelihood that someone is just trying to get out of paying for something for which they did actually understand the cost.
Amazon also has an interest in keeping their customers happy, and keeping usage growing. A customer who gets a refund for accidental or fraudulent usage is much more likely to remain a loyal customer, and hopefully spend more on the platform in the future. A restaurant, while in the hospitality industry, is likely more concerned with their razor-thin margins.
Also I would expect the true motive in your example is that the restaurant-goer is trying to scam the restaurant out of an expensive bottle of wine, and I'm sure most restaurant managers would agree with me. The AWS customer is not only more likely to have made an honest mistake, but AWS support has tools available to look at the usage and make a more nuanced decision as to whether or not the customer is telling the truth.
(And I have witnessed quite a few situations where Amazon has written off usage bills in cases like this. So clearly they agree with me on this, at least some of the time. Not all of the time, of course, as the grandparent poster can attest to.)
A restaurant has an interest in keeping customers happy, and keep recurring customers growing.
I would also expect, that the average cloud user made a mistake a professional should not have made and is now trying to get out of it the easy way. I mean, what do you expect if you post your credentials to GitHub (just an assumption)? Same as if you order wine without looking at the price. Your fault.
Also, a single bottle of 200$ is minuscule compared to the monthly/yearly renting fee a restaurant needs to pay, which can be many thousands.
Long story short: IMHO it all comes down to how good one can tell that it's really a mistake and there were multiple mistakes which could hardly be avoided which lead to this issue.
I would be shocked to find a cloud provider doing that, but I wanted to point out that you might be not have made a real mistake.
