The JW's tell you what to wear after assemblies, what hotels/motels to use, what food to bring, how to behave in hotels, not to leave convention site for lunch, not to buy from vendors outside the convention site, be in your site before the musical interlude. Yup, they sure don't micro manage. Not one bit. Can't leave anything up to the faithful.
Jehovah can trust the rank and file with delivering the important life-saving message, but can't trust JW's to come back to the convention when they go somewhere else for lunch.
