cancellation of website

I've just received a call from British Waterways. They have been 'tipped off' by someone that I am running a business (The Narrow Way) without obtaining a BW commercial licence. I explained that, so far, I have had no customers and so could not afford to get a commercial licence (which costs around double the standard licence) He was a nice man and said that it's a difficult thing to set up a business with all the costs involved without any income. However, he was clear that, if I am advertising The Narrow Way, then I must, not only get a commercial licence, but also have to adhere to the same rules and regulations as the 'big boys' like the hire companies. He directed me to a website with all the rules on it and having looked at it, I'm reluctantly having to withdraw the Narrow Way website and stop offering the boat for paid quiet days.
I'm not going to waste time wondering who the 'tip off' came from, although it's tempting to speculate. Suffice to say I'm fairly gutted - particularly as my friend Maggie has spent so much time assisting me in setting it up. Thanks Maggie! I'll just have to find another way to make some money I guess.
