I was the primary ops guy (well before the concept of devops and when separation of duties was important) and ended up being the primary troubleshooter for problems. During one of the meetings between DEV, QA, RC, and I, the software architect exclaimed that RC had to be exaggerating since he just said it took X time to transfer the installer from one machine to another.

I looked at him and said the installer is ~200MB in size, 20 seconds is more than reasonable. He started arguing that the network connections had to be at least 100meg links so it shouldn't take more than 2 seconds. It went round and round, until I realized he didn't understand that network links were in bits/sec. At this point, he was refusing to listen and started disparaging everyone 'against' him. I gave it one more go and showed him the unit conversion and basic math on file size, rate, and time.

For a while, it looked like he was trying to get everyone arguing against him released since he was an 'architect' and everyone else was engineers and I was just the ops guy. Too bad for him, he didn't realize in the land of inflated titles, I was the security, storage, and infrastructure architect. I just felt it was presumptuous and relabeled myself the ops guy.
