Just wow...
First off, you are comparing doing your job to Nazi soldiers "following orders". Last I checked, they weren't asked the "difficult" task of just smiling and being polite. That statement alone takes away what very little credibility you had.
Second, you have no idea how many people in this world confront trauma and don't kill themselves. I've lost people VERY close to me (by suicide even), been homeless, taken advantage of, humiliated, embarrassed, and called names. I've been fired for not doing my job. Battled depression too. Yet, here I am, still reading and responding to your nonsense.
Not once did I believe it was my employer's responsibility to make sure I wanted to live each day. Their responsibility is to make sure their business runs smoothly, and effectively. Can they handle some things differently at times, yes. They are human too. Your job is to do what is asked, as long as it is legal. Last I checked, being polite at work is legal all around the globe.
In my job now, there are plenty of people I don't want to be nice to. There are even more that aren't nice to me. But see, I'm what you call a grown up. I understand life is difficult at times, and it is my responsibility to improve that, not everyone else's. I also understand that I have a job, and that job entails being nice when I don't want to be, working 7 days a week for sometimes 12 hours a day, smiling when I don't want to, and not projecting my attitude towards others when I am not feeling like being nice.
I think everyone can feel for someone battling depression. That does not make it everyone's responsibility to give that person special treatment, or allow them to ruin their business.
