What nourishes your soul ?

There are times when I'm working greeting customers and there are afternoons that most customers, hundreds of them, turn their faces the other way to ignore me and walk by( happens to other greeters too) or say something rude or have an impatient moan-sigh- tone of voice when I'm labeling their returns. I stand there thinking about getting a job somewhere else and then along comes one dear stranger who needs a hug or another that says something so sweet & kind that it surprises me or service manager pats me on the back complimenting me for something I've done. Those are the little things that keep me going and the others in my job too. Not all days are so bad but I have wondered lately if the handful of very kind strangers who I've seen only one time and never again were sent by an angel to give me a little support.
