Kick him in the small of the back while walking in to Tesco?
Popped over to tesco and on the way in the family in front of us behaved like this.
Small boy (who was walking) hit the leg of his sister who was older then him but sat in the trolley and the "mother" screamed at him don't fucking do that and kicked him in the back
It was all I could do to stop myself doing the same to her.
Bitch!!!!
