When I was undergoing Bible study in India, I went to the convention for the first time with a one day beard. At the convention my BS conductor asked me why I wasn’t clean shaven. Hell... I should have recognized this is a tight control cult. But no knowledge about cults then
When I arrived in USA, I went to the FS without wearing a tie. Immediately the FS conductor gave his spare tie to me and told to wear it.
Actually in India, nobody wears a tie out in FS and most JW men wont even tuck in their shirts for the meetings, FS and assemblies. It’s a culture thing and also due to poor economic conditions.
