Bob goes to a burger joint every week for several months and orders an individual beef patty for £4 which they are able to put through on the till as an “extra.”
One time Bob arrives at the place and orders his usual and the restaurant delivers his order but then brings a bill for a full burger charged at the standard price of £10.
Bob protests this but the restaurant explains that since the old manager was replaced that week, they have changed their policy and no longer allow selling only a burger patty without charging for a whole burger. Bob offers to pay £4 like he always does, if they will put through such a charge on the PDQ, but no more, and certainly not £10.
The restaurant insists on charging £10. Can Bob leave the location without being guilty of an offence?
Then suppose Bob changes jobs the next week and no longer happens to work near the place, so forgets about this whole shift and resulting kerfuffle in the transition of his daily routine, until one evening a year later he finds himself in the old area for an appointment after which he finds himself walking by his old local lunch haunt.
He decides to stop in and order his old usual, as he always used to, “just a patty without the rest of a burger; basically only the beef, medium rare”.
Then the bill arrives again at £10, and Bob asks why it is different from how it always used to be. The same manager as was me the last time reminds him that they’d been through this once already before the prior year, so Bob should have already known what he was getting into, and Bob sort of vaguely remembers at that point but still barely recognises the new manager that he is now facing having only met him once a year ago and that when he was going through a major transition.
Anyway, what is now the legal position the second time around there having very arguably been no genuine meeting of the minds as to the terms of the formed contract?
