Phubbing (verb) the act of snubbing someone in a social setting by looking at your phone instead of paying attention.
A campaign had recently been launched in Australia, to stop Phubbing. http://stopphubbing.com/
It does make me sad that there is a need for a campaign to remind people to be polite. Not acknowledging another person who is working to provide you a service it completely inexcusable and the height of arrogance. Spending time with friends and family staring at your phone and not at them is just rude. I highly doubt you will be talking to someone on your shiny smartphone about an awaiting kidney transplant whilst ordering a skinny latte. So put the phone down!!
I, Dear Reader, love my phone but treating others with dignity and respect is far more important, so next time you are out with friends or someone is providing you with a service, treat them as you would want to be treated remember to make eye contact and don’t forget say please and thank you.
