I could be wrong, but this is a change related to the $13 million payout to those molested recently. Book studies in private homes are usually more relaxed with people sticking around to socialize. ( Had a book study in my home for 3 years.) Pedophiles can more easily have an opportunity to seek out victims. "Hey, I need to use your bathroom, ok?" As the walk past kids bedrooms...etc. Lawyers see lawsuits on the horizon…better safe than sorry (not for the victims ,of course, but for the pocketbooks of WTS). If it was because of gasoline prices the idiots would cancel the 3 day conventions. Just my opinion.
