I went to highschool mostly in texas, which means recruiter creeps in the lunchroom pretty often.
they'd usually have chudlets doing pushups in the middle of the lunch room, but sometimes they went out and used their social skills to try to recruit people. One time a guy in my friend group got his lunch and sat down before any of the rest of us, and a recruiter strolled up and sat down trying to have a conversation with him. He asked if he liked heavy metal (context clues, we were goths) and he said "no, I don't like music" and just stopped eating and made direct eye contact with the recruiter. The recruiter stumbled a bit and then asked... "uh, do you like blowing stuff up?" My friend's response was "no that's fucked up what's wrong with you, fuck off" and the recruiter awkwardly walked off while the rest of us were walking up to sit down.
