Damn! Hit the 'Enter' button prematurely. There IS NO WAY TO DISCONNECT from the registrar politely, without registering. Every reason or excuse will be met with a seemingly-reasonable response. BE PREPARED TO BE RUDE if (when) you find this happening. Seriously. The English, and especially Londoners, have a reputation for being polite (that's a compliment, if you're wondering)---$cientology registrars use courtesy as a tool to manipulate you, and will not give you a polite way to leave during a "registration cycle". My personal advice is, don't go inside a $cientology Org (church) unless you are prepared to BE RUDE when (not "if") necessary: Be prepared to say, "I'm done here!" and mean it, and turn your back on someone talking to you and walk out of the building even though they're calling "polite and reasonable" questions to you as you leave. If you stop to answer, --they've hooked you back into their well-rehearsed protocol for registering you. No matter how well-reasoned or logical your answer, they'll have a 'reasonable' response that will keep you engaged. Again: if you are not prepared to be rude when the time comes--and it probably will--then you have no business going into any $cn Org/church/mission. If you take a friend, be sure your friend is prepared to follow your lead and leave with you.
