The proper response to "Thank you" is "You're welcome". The proper response is NOT "No Problem". If I wanted that response, rather than saying "Thank you", I would've asked "Was that a problem?"
Am I the only one annoyed by this usage?
P.S. I've heard "competency" used at least a half-dozen times this week. Kill me now. And, ironically, killing is something Marines are good at...part of their competence. Which shouldn't be a problem.
