Is customer service fully gone?

I need to know this. Had to yell at a customer today and while it felt good, I realize this could pose an issue to my job. Before anyone may get mad at me for yelling at her, I did try to be respectful towards her and only snapped when she said she was happy we were losing our jobs.

My store manager says it's gone but I just wanted to check.

If my coworkers see this: omg hi guys :)
