A local cinema's shitty website charged me and, immediately after, my wifi disconnected for a few seconds. This somehow crashed their server entirely for several minutes, failing to send me the tickets even when it got back up.

It took me several threatening emails to make them understand they had already taken my money and I wasn't going to try again until I got a refund. Now I'm paranoid any time I purchase online at mediocre shops.

I tried subway online ordering once almost a year ago. The last final screen crashed and deleted the entire order from my cart. Anyways, you're probably wondering if the order actually went through but subway's UI was shit and nearly tricked me into replacing the same order a second time: yes.

out of curiosity, what's the technical solution? My guess: add an idempotency key to the request and a message queue? Then when you try to consume it, you check whether that request was made previously.
