I just felt this recently. I was sent some code for me to put into prod, a long running service. And in one func, which returned an error (Go) but still called "os.Exit" in each error handler rather then returning.

Fixing the issue was a small matter. But the amount of disrespect I felt, that I looked at it closer then anyone else apparently (which wasn't really all that close at all), when they were ostensibly building this code, that disrespect was just immense.
