I hate smoking while walking down the street, If I want one I'll sit next to a bin with a 'grid' on the top. I also have a small tube thing that you can put the stub in that puts it out when you seal the end and dispose of it later. I only smoke in the downstairs loo so not to spoil the house, bought a flat once that when the previous owners moved out the walls were yellow apart from where furniture had been pushed against them.
Also, where I used to work, it took 5 minutes to smash the ciggy bin off the wall but 6 months to fix a PC!
Can't stand people that don't pick up dog 'bits' or if they do they then hang the bag on a tree!
