When you ask someone for something and they say this is how we've always done it. 😩😩😩. I die a little on the inside.

Get used to it. There are many people like that. They eventually change or more likely fall by the wayside.

My biggest pet peeve is someone saying, "this is how we've always done it, so we're going to keep doing it that way."

No. Give me a reason that this is the best way of doing it, and I will listen and potentially embrace it. Tell me that you're afraid of making things better and I'll find a new job.
