While I was working an overtime shift I stopped at a local sandwich shop to grab lunch. I had shown up just in time because a long line soon formed behind me (and no I wasn't taking that long to decide).
After paying I made way toward the exit. In line was a woman with her 12 year old daughter and her daughters friend. As I passed them the shouted, "Thank you for being a fireman!" That's humbling. At least it is to me.
All I could say was thank you for letting me serve you. I have the best job in the world and I get compensated well for it. What else can be said?
