So to cut a long story short I'm a cleaner and my managers came in today saying they were doing an investigation cos a customer complained I'd stolen something from her obviously I had no idea what they were talking about but they said they had me on cctv which showed me picking what i thought was rubbish up off the floor and putting it in my pocket til I was near a bin turns out the rubish was in fact a packet of cigs that belonged to a customer I don't remember doing this as I work in a busy supermarket and I'm forever picking things up now ive got to have a disciplinary surly I can't get sacked for something as trivia as this please help
