Usually, no one would have cared or known if a neighbor did not report it. You have some choices change incall locations often, use hotels or weekly stays, if you have a garage have the client park in the garage and close it (great for regulars) or park in the rear. Meet the client in a public place and maybe have the customer park across the street. If you live in a older neighborhood where older people are, you may want to introduce your self and tell them you have a home based business and have people come to your home often. I don't do incalls where i live for this reason.
