Problem question (p. 175) Ming runs a hair salon called Australian Hairlines (Hairlines). Ming decides to promote the business by advertising a 'special offer' in the local paper. The advertisement he places in the local newspaper states that 'Hairlines' will, on the production by the customer of the advertisement, give that customer a haircut at the low price of $10. The day after the advertisement is published some 50 people arrive at the salon asking for the special haircut at $10. Ming is overwhelmed by the response and realises that the salon will lose a lot of money if this promotion continues. Ming decides to put up a sign in the Salon's window which states THE OFFER OF HAIRCUTS AS ADVERTISED HAS NOW FINISHED. Explain the law as it applies to the following persons: . Forty customers produce the advertisement before the notice goes up in the window. Are these customers able to enforce any legal agreement? Explain with reference to contract law. . Ten customers do not have the advertisement with them, but still want to participate in the promotion. Are these particular customers able to enforce any agreement? . Could Ming argue that the payment of $10 is insufficient for the promise of what would normally be a $60 haircut, and consequently there are no legal obligations on the business? Ming believes he has now withdrawn the promotion and has no further obligation to provide cut price haircuts. Is this correct
