Etiquette authority Debrett's has come out with a guide on how to queue correctly.
Jo Bryant, etiquette adviser for the specialist publisher listed recommendations on how to conduct oneself while standing in line, reports The Telegraph.
These included:
"Be patient. Remember that everyone's in the same boat, so avoid displays of exasperation or aggression."
"Be aware of other people's personal space and don't stand too close to the person in front of you."
"Even in the most disorganised of queues, there will still be an unspoken order."
"Where there is one queue for multiple till points, pay attention; don't hold up the queue by failing to notice when it's your turn."
"If there are lots of queues, take your pick - but if you choose badly, accept the fact that some will move faster than others."
"If you are unsure how the queue is working, avoid accidentally barging in by asking the person who seems to be last in line."
"Keep shopping bags or trolleys close you, to avoid creating a big gap that can confuse people trying to join the queue."
"If you are required to stand back and wait your turn, don't move forward until the person in front of you has finished. Never try to hurry them along."
"Have all relevant documents to hand and ensure you can locate your purse quickly to avoid holding people up."
"If you realise you've forgotten something, don't ask the person behind you to save your place; you will most likely make them feel uncomfortable. Join the back of the line instead."
