��50 notes are legal tender, which means they cannot be refused if offered as payment for a legal debt.In a shop a legal contract is not created until you take the goods to the till (which is an offer to purchase) and the shop then asks you for payment (they accept the offer).If a shop has a sign up saying they don t accept ��50s then they are making this a part of the contract, so they don t have to accept them. Technically you would be in breach if you had no other form of payment, but in practice they would just cancel the deal.But, if there is no obvious notice then the shop has no option but to accept you ��50 note, because there is a legally binding contract and they cannot refuse legal tender in settlement. If they refuse to accept it it is them who are breaching the contract. Technically the goods would be yours and you could leave with them (although good luck in getting PC Plod to accept this). You still owe the money and must pay it, but it is a civil and not a criminal matter, and you can continue to offer the ��50 until it is accepted.
A shop can refuse *anything*. Until you have actually made a purchase, a shop has no legal obligation to a shopper. (Apart from peripheral things like Health and Safety). It doesn t have to sell you anything if it doesn t want to.... etc.It s not illegal to refuse your custom either. Mind, they d be daft to do it without good reason.
It would depend on the circumstanceif they believe it to be fake then yes or if they Simply do not have enough change to give you if you pay with a ��50 note. However if they do not have enough change they can only ask you to pay by another means...they cant refuse money as that is refusing your custom.
Yes they can. My business would never accept a ��50 note as there were and still are, a lot of fakes around. Definitely not against the law.
