While 75pc of US adults thought mobile phone manners have sunk in the past year, some 20pc have admitted to poor mobile phone etiquette themselves, a survey by Intel suggests.
Most people, according to the survey, said mobile phone etiquette is not improving.
Behaviour such as texting while walking, sending a text message during dinner, or gabbing loudly on a mobile phone while on public transit annoyed most of the 2,000 survey respondents.
A quarter of respondents said the lack of manners has spawned a new form of public rage, with 65pc admitting they grew angry around people who exercised poor mobile phone manners.
What really bugged people the most? The use of a mobile phone while driving, talking loudly on a mobile phone in a public place, and walking on the street while texting or talking at the same time.
The survey respondents also said they see an average of five mobile offences daily. Nearly 25pc said they have seen someone using a laptop while driving and one in five said they check their mobile devices before even getting out of bed in the morning.
