Brits are most well-known for donning their shorts when the sun comes out, and sticking the kettle on in times of crisis.
That is the revelation made by Tetley following their commissioned 2016 Britishness Audit.
Two thousand adults were questioned on what they thought were "typically British" traits, with having a dry sense of humour, forming a queue at anything and not wanting to cause a fuss some of the most popular choices.
Cassie Shuttlewood, Senior Brand Manager at Tetley, said: "Our new ad is all about celebrating Britain’s greatest moments – the people and events that fill the nation with pride.
"And we wanted to explore this a little further with our audit, shining a light on how Brits feel about the country and the things people associate with Britishness."
Other "common" British traits include having a beer at the airport even though it's before 8am, giggling at innuendos and mistaking brightness for warmth.
