Additionally having a narrow viewpoint of a situation (at a restaurant, eyeballing some receipts) and assuming you've seen enough to identify the root cause of a problem. There's a pretty large assumption that the cause was mishearing or misreading the order identifiers. They had apparently personally experienced a "swap" twice, but made no mention of whether this was the cause.

However I don't want to dump on the guy too much, he broke down what he thought was the problem, and attempted a solution and did so with a bit of humility ("I hope it's clear that I don't think I'm smarter than anyone at Uber, Uber Eats, or really anywhere").
