I was queuing up today in the supermarket and waiting to put my basket of shopping onto the belt by the till. I could not move forward as the people in front of me had their trolley in front of me although there was space on the belt. The man behind me stood next to me, instead of behind and then without warning grabbed the handles of my basket to try and push/pull me forward. I immediately said 'Get off , what are you doing?' There then followed an exchange of words , he said he was 'being kind'. He was about sixty and quite a big build. He then decided to move to another queue. I felt quite shaken afterwards . Just wondering WWYD?
