We’ve all got a tight mate who mumbles ‘I’ll just sort myself out thanks’ when you generously offer them a drink.
Even when you’re in a Wetherspoons, they’ll refuse to take part in the beautiful communal activity of buying a round.
Every 45 minutes (ish), one person gets to feel like a legend, treating their friends to their favourite poison of choice, while the one friend in question sits in the corner, going up to get their individual beer.
Amy Morin, author of 13 Things Mentally Strong People Don't Do, told UNILAD:
Psychopaths are probably least likely to go in on a round of drinks. By nature, they are non-cooperative and lack remorse. They also tend to violate social norms.
They are capable of exhibiting superficial charm, so they may occasionally show kindness but only if it will serve them well.
A 2010 study published in Neuropsychologia found that in economic games, psychopaths are the least generous.
People who are agreeable expect others to reciprocate and behave cooperatively, but psychopaths don't expect that from others so, they may expect to be taken advantage of if they go in on a round of drinks.
People with borderline personality disorder, which is a mental illness characterized by mood instability, difficulty maintaining healthy relationships, and impulsive actions, have a striking deficit in trust and reciprocation.
So they may be less likely to buy a round of drinks because they don't trust others or because they fear being taken advantage of by other people.
Yet, they're impulsive so they may surprise people once in a while by spending a lot of money and buying everyone in the entire a bar a round of drinks.
A survey with a sample of 1000 respondents found 85 per cent of people participate in buying rounds of drinks, but 81 per cent of us would rather buy our own.
Steve McKeown, founder of MindFixers, explained how people who actually voice the desire to go it alone in the pub are actually more self-assured and don't succumb to peer pressure.
Steve McKeown, Psychoanalyst and owner of The McKeown Clinic, told UNILAD:
People that can avoid the implicit and explicit pressures of entering into round buying are more self assured independent thinkers as they show an internal locus control which makes them more autonomous to their social environment.
These types of characters show they simply do not bow down to the peer pressures of their social groups. They are leaders not followers.
Major factors to why people tend not to participate in 'round buying' is due to over consumption of alcohol and cost, which increases their overall alcohol intake through implicit and explicit pressures to consume more.
Leo would always go in on a round...
Although you're more likely to be a psychopath, if you do wish to resist the social pressure of rounds, then Steve suggests quickly saying 'that you don't want to do a round before anyone buys you a drink'.
Probably best to just get in on the round to be honest.
