The venue organizers also ended up with a shit experience (and angry potential customer) while having nothing to do with the BS.
An angry potential customer who demands one work for free is probably not the kind of business arrangement that most folks would find agreeable. I don’t know where these people get off, but they’re free riders on the information superhighway. If wishes were horses, beggars would ride.
Instead it’s the worst outcome for everyone, and everyone is angry and thinks each other are assholes. I guess that does sum up America the last few years eh?
His problem.
Frankly, most people would be angry in that situation.
There are reasonable reactions in this situation: Either be grateful that you got something for free, or accept that you were misinformed and pay what is asked, alternatively leave.
But let's be honest about this particular situation: The visitor had checked the event online, maybe first with ChatGPT and then on the official website. They noticed that the AI had made a mistake and thought they could abuse that to try to get in for free.
Everybody who works with the general public for restaurants, hospitality, events or retail recognize this kind of "customer", who are a small minority which you have to deal with sometimes. There are some base people who live their lives trying to find loop holes and ways to take advantage of others, while at the same time constantly being on the verge of a massive outrage over how unfairly they are being treated.
A base and egocentric person.
Unreasonable people are wrong to be unreasonable. This is not new. Technological solutions don’t map to problems of interpersonal relations neatly, as this example shows.
