I have a regular who's a retired SEAL. Nicest guy you'd ever meet, and with a great sense of humor.I really, really wanted to tell him I just got a job administering contracts like his, wanting to know all about it, 'they' had hired me but told me nothing for security reasons, but I didn't have the heart for it right then.
I mention that last bit because he was standing at the counter when a 20-something kid came in and started waxing poetic about his time with the SEALs. I started to worry until the real guy leaned over, feigned fascination, and asked the kid to tell him everything he could because "that's just so cool."
The kid went through a litany of stuff even I could tell was bogus, and he did it for about 15 minutes to a guy who'd really been a SEAL. It was priceless.
