Today's Times reported that Sainsbury's has been forced to apologise following an incident in a Brighton store.
According to the paper, Annabelle Paige, a 22-year-old English literature student at Sussex University, was stopped by a female security guard when she was with her girlfriend.
The security guard had been approached by a customer who saw Paige give her girlfriend a "light kiss". The security guard told them to "take it outside". Paige, who had considered speaking to police and is now consulting a lawyer, said she was "really upset".
The incident happened on October 11 – National Coming Out Day.
A spokesman for Sainsbury's told the paper: "This should never have happened – it is clear that Miss Paige and her partner were not behaving inappropriately and we are very sorry that they were treated in this way. We have called Miss Paige to apologise and will be making a donation to a charity of her choice."
