You just reminded me. I was on a longish bus journey yesterday and the two opposite me were munching loudly all the way. Grrr. They didn't even share them!
I found those little boxes have re-emerged that you used to get from the cinema. About twice the size of a fag pack and filled with either Smarties, Wine Gums or Fruit Pastilles. Oh how I love fruit pastilles. I wish I had never seen those little boxes.
