A Sydney commuter has been slammed after he was caught reminding himself to send a "break-up email" with a note written on the back of his hand.
Footage of the man was posted to TikTok after radio host Emma Chow spotted him on her train carriage on the way to work.
"Is this the most gutless way to break up with someone?" she captioned the video.
TikTok users were divided when they saw the footage, with some claiming he was unprofessional and "brutal".
"Imagine the sign off … live, laugh, I don't love you," one woman commented.
