I was once contracting at an ISP/telco in the naughties. While working on a UI to obtain PAC codes and transfer phone numbers, I was coding a modal confirmation dialog, when I almost unconsciously translated the specified "You sure" into "Are you sure?".

The QA guy kicked it back. So I took it a manager to get the spec corrected. The manager said to just follow the spec as written. No, I couldn't add a question mark. Apparently the company used language like this to appear "down with the kids".

I hadn't realised I had got so out-of-touch. So I went away and did as I was told. Oh well - I'm still here, but the telco isn't.
