I was positioning in uniform on a flight just behind the overwings. During the "please keep your seatbelts fastened, phones off, bags stowed...." pa on taxy after landing, I looked up and noticed a vs crew member texting away on her mobile. I stood up and walked two rows forwards to ask her to switch it off.
Though just 2 weeks later I was positioning again and another commuting crew member switched on his phone, which had received a text, prompting the crew just behind him to pa for phones to be switched off. I noticed it was him, he looked up and grinned then covered his mouth with his finger as if to say shhhhhhh!!! I was stunned.
