I hate to hear a story like that.
As a Marine, I hear the question, "Hey, anybody got a knife?" at least once a day. I don't really have a horror story, as this question is usually followed by, "what for?". Then, based on the merit of their explanation, and my own split-second analysis of the likelihood of my knife being damaged they may or may not be loaned a knife. Usually they are not.
I continue to be amazed by the sheer number of people among us (to say nothing of Marines) who don't carry a knife. I am further amazed by the tasks that a person will subject a knife to, when, with minimal effort they could get the appropriate tool for the job.
