ALL loyalty card holders must show complete obedience, supermarkets have announced.
Nothing comes for freeCardholders must renounce all other supermarkets and be prepared to unquestioningly follow orders from their favourite chain even if it means killing their relatives.
Sainsburys executive Nikki Hollis said: Customers will have to prove their loyalty in a variety of ways, for example by buying a whole shelf of pastries or pistol-whipping an undeserving fellow shopper.
Alternatively we might order them to work on the tills if were short-staffed, or to firebomb Aldi.
Refusal will result in them losing all their Nectar points and being sent to a Sainsburys re-education camp.
A Waitrose spokesman said: Were on the lookout for signs of disloyalty to Waitrose, such as a Tesco Clubcard in someones purse or a casual reference to how cheap Lidl is.
Their right to free tea and coffee will immediately be rescinded, with repeat offenders receiving a visit from a gang of hired thugs in an Ocado van.
Shopper Tom Logan said: The staff in Morrisons started screaming and punching me when they saw my re-usable Co-op bag, but with a qualified in-store fishmonger whos going to complain?
Also Ive heard that if all the supermarkets disown you, you have to live on Happy Shopper products.
