McDonald's Criticized For Incorrect Brit Slang: Bob Not a Pound
A 'bob' is a term for a shilling, or five pence, and of far less value than a pound. Some customers have asked McDonald's to correct the advert or withdraw it, or allow them to purchase items on the Saver Menu for a true bob, or five pence.
Their spokesperson told Sky News, "Although a 'bob' was formerly used as a slang term for the shilling until the introduction of decimalization in 1971, research has shown it is now more commonly used as slang for a pound or money in general.As with many words in the English language, the technical meaning of words can change over time and although the word remains in use, what it signifies may develop into something else.''
A quid is English slang for a pound. The term 'bob' is not commonly used now, but is still used as multiples of 5 pence as in '5 bob' for 25 pence and '10 bob' for 50 pence.
