When I went to Pontins in the 70s as a child(And Butlins) I was allocated a dining spot and house, you could either be in Embassy Regal house or Benson And Hedges house, this is no joke. You sat in the area designated with the ciggy signs at each end of the mass dining hall.
As kids we would hang around the arcade and question other kids as to their cigarette house preference, quotes of "you Benson and Hedges b,stards" would go around and a few fights and attacks would take place all in the name of our respective cigarette house.
This hate was propagated by blue coats. At the swimming pool events we would be asked our cigarrette house by the blue coats, only to be booed or clapped by Benson and Hedges people. I cleary remember kids chanting down the mic "Embassy Embassy Embassy" and goading on other people from opposite houses.
Kinda mad when I think about this.
