A new study revealed that British people are not willing to wait in line for more than four minutes.

Those aged over 55 are the most patient, admitting they are happy to queue for a full four minutes, while younger Brits are less prepared to hang about.
Those aged 35 to 44 will typically queue for no more than 3 mins 40 seconds, and 18 to 24 year olds will stand in line for no more than 2 minutes 59 seconds.
It seems men are less patient than women, content to queue for just 3 minutes 23 seconds - compared to women at 3 minutes 39 seconds.
