It's about presenting a professional image in front of the pax and the cc failed to do so. Read the company handbook then, what do they say about once you don yourself in the uniform? I have to agree with samurai.
And sorry, being a regular pax on ANA and JAL, I have never seen this kind of problem samurai raised. They are very professional before and after flight, even when waiting for their luggage; definitely very different from chatterbox texting cx cabin crew. One does not only do it for money.
