I doubt that this is the first time she never received a tip but since it was a church she probably felt that she would get a lot of sympathetic people on her side. Well she got at least one unsympathetic person and it was her boss. Bye bye.
I’m pretty sure this was the first time she ever had to assemble a huge order and been stiffed in the process. Church or not. Looking for anti-religious bias in all things is very unbecoming.
