Postie voted 'friendliest worker'
Train and bus drivers are the unfriendliest workers in the country, according to a poll.
Postmen are considered to be the friendliest with 36% of the vote, followed by pub landlords at 33%, and tradesmen at 29%.
About 84% of Britons feel we should be more friendly to each other, but more than half would ignore a stranger in a pub rather than start a conversation, research for Guinness found.
And while 20% of people were happy to hug their friends, a quarter of the men questioned said they would be too uncomfortable to embrace another man.
Traditional views of the north-south divide continue, as 43% of respondents said residents were more approachable in northern England. Two-thirds said London and the South East were the least friendly areas.
But simply smiling at someone was considered to be the best way to be welcoming, according to more than half of the 2,000 people questioned.
The X Factor's sharp-tongued Simon Cowell topped the list of unfriendliest celebrities, with model Naomi Campbell - famous for her diva-like behaviour - and gruff businessman Lord Sugar completing the top three.
Dancing On Ice presenter Holly Willoughby was voted the friendliest famous face, followed by co-host Philip Schofield and Girls Aloud star Cheryl Cole.
Guinness commissioned a Onepoll survey of 2,000 people as part of its "friendliness" campaign, ahead of St Patrick's Day on Thursday.
