You will find that if you eat a Kit Kat on the job, the wrapper becomes "trade" waste, and if you carry it in your vehicle, no matter where you take it, you need a "Waste Carriers Licence" from the Environment Agency, doesn't matter what you carry it in, car, van, tipper, pushbike, or where you take it, up to £5000.00 fine and or imprisonment if they go for you.
Get customer to dispose of it for you or have a skip, of course make sure your "Public Liabilty" is up to date cause if someone hurts themself you will be liable, my re-newal has just come in at £341.25
Yea I do use a skip sometimes, depends, as if your not carefull some usless peices of shiite fill it with their rubbish overnight, then it costs double, all tax deductable, but if it costs £55.00 you dont get £55.00 off your tax bill do you.
