Sainsbury's worker refuses to serve woman on her mobile

Jo Clarke, a 26-year-old property manager, was shopping in Sainsbury's in Crayford, Kent, and chatting on her mobile phone, when she was surprised to receive a lesson in mobile phone etiquette from a member of checkout staff. The staff member apparently refused to serve her unless she hung up.

Sainsbury's has apologised, and said this is not company policy. But there are mixed views on who is in the right here.
