I do this, sometimes. And it's fine.

Especially not on live ... it never happens man. It's urban legend.

You're implying this does happen. Where does this happen? I've never experienced it.

I did have a guy, supposedly experienced, push some code to master that he had obviously not run because it still had obvious syntax errors. I can only assume there was a bit of a culture mismatch, but still, shall we say I was peeved.

It's more like deploying code to production without at the very least running it once. That would be really fucking dumb. Most people don't do that. The above comment is saying that most cookbooks are hot garbage and dont have recipes that have been used once.
