For many a traditionalist, 'thank you' is the most important two-word phrase in our vocabulary.
But, it is falling by the wayside, replaced increasingly with less formal expressions of gratitude, a poll reveals.
Millions opt instead for the more casual 'cheers'. While the average person will still choose to use 'thank you' nearly 5,000 times a year, one in three replaces it with 'cheers' or 'ta'.
One in 20 says 'nice one', while younger generations are more likely to offer 'cool'.
'Merci', 'fab' and 'much appreciated' also emerge as popular alternatives in the poll by Food Network UK. Nick Thorogood, managing director of the TV channel, said: "When it comes to saying thank you, people will always find the way that works best for them."
