Incompetence at that level feels like malice.
Fortunately, you have more power than you think. Just don't do business with these companies. Picking a hotel and calling them directly always works for me.
One could also open the DevTools, Ctrl-F for part of the address, and copy it from the HTML source...
Google and many other services direct you to the hotel itself, which means you need to create an account at the hotel's and enter your cc data... so yeah, tough luck if the hotel's 1990 era website gets hacked. Meanwhile, for Bookingdotcom, I enter my data once, don't have to worry about newsletter spam for the hotels, or my credit card data being exfiltrated. And same for airfare or train rides that can't be booked on Deutsche Bahn.
There are plenty of full service travel agencies that offer to book guaranteed price reservations in pretty much any locale in most countries. There are some that even offer extra guarantees like a last minute cancellation by the hotel being refunded at double the cost, to ensure you can get a room elsewhere.
Because you live in an attention economy and the probability of using another service is pretty low. We can also develop our own travel agent with LLMs but that's an outlier of the market, and financially negligible. The problem is about power in the economy.
If a dozen different HN users expressed a dozen different preferred ranges… would there now have to be viable competitors at each possible step?
This is an ironic statement, insofar as it's myopic.
The implication was clearly a monopoly by market availability (convenience), which is not a legal precept, but a sociological one. Comparing rates across all possible locales and vendors is impractical. This is part of what makes Amazon so successful. Sheer momentum.
Then, the consumer criticizes those of us that enjoy backpacking as not being "adults". This one really got me.
The concept that advertised prices that are genuine mistakes are generally not enforceable is a well established concept in many jurisdictions.
With that being said, I do believe that honoring ones advertised prices, even when they are mistakes, unless it would be egregious or impossible to do so, is generally a better way to do business.
But will this story prevent me from using a convenient and less expensive platform for booking cheap, bottom barrel hotels, for those of use who aren't "adults"? Probably not.
Will this public case result in flood of people away from booking.com? Probably not.
This is just a simple abuse of power, most easily identified by the question: "What are you going to do about it?"
It seems the play is to tell the world. Congrats to this lady for getting her money/booking back.
