I wondered if all window cleaners paid tax and were some claiming the dole while doing the job? If this is the case could the tax man or job centre police use a photo of you face on (in a flyer) as evidence that you are working or would it be wise for the person making their flyer not to put a photo of themselves on the flyer at all? Or perhaps have the photo with them working from behind so their face isn't seen on the flyer?
