Thats bad business practice though, Leg! I have worked for 2 major pub chains and the big coffee chain and cigarette butts in the doorway would have lost me a bonus. Shops, pubs, cafes etc should be keeping them clean, and the area outside their establishment, even if their is no pavement cafe.
One of my friends has a little keyring ashtray. She hates fag butts on the floor that much. We were sat outside work and she was smoking and she was putting the the cigarette out under her shoe, when a female PCSO fined her. She showed her her ashtray which I can vouch she would have picked it up and put it in, and said I haven't finished putting it out, when I do Ill put it in here. he told her she could tale it up with the council, only to be told because she accepted it she had to pay the fine. 50 quid for a fag, after witnessing that, I would never ever put a fag out on the floor. The butt will remain in my hand tii it hits the bin.
