I don't know the complete ins and outs of the rules set out by these associations but I would have thought that they would have to have some sort of base to work from, or I would hope they would have to.
Without looking and finding out I do not know, but I am with you on this one - it does sort of throw everything out the window a bit if they are working from their car!
We will have to look at their rules to find out the answer. |
