Very few "interested" people ever came along and those that did wouldn't really be of the type to notice much of the meeting , but were likely more to be affected by the "love bombing".
I recall a funeral when a solicitor came along who was handling the deceased ladies estate & the elder ( one of our poorer speakers ) stuck rigidly to the standard Society outline talk without much mention of the JW who had died. The solicitor shook his head a few times and looked a bit uncomfortable ( I was standing at the back of the KH ). Frankly - it was a bit of a car crash of a talk from a non JW observer point of view but as usual the congregation knew the score and took it all in.
I knew him slightly in a work context as he was engaged by the firm I worked for to do some legal work and a few weeks later we had the quarterly meeting with him and I got chatting to him afterward over a coffee.
He mentioned that he had seen me at Mrs Xs funeral and asked if how I knew the lady. I had hoped he hadn't seen me or wouldn't mention it , but had already anticipated the question and formulated a response. Like many JWs , I always tried to keep a very low JW profile at my work ( most people weren't even aware that I was a witness ) , so I just mumbled a reply to the effect that my wife was a JW and I knew Mrs X through that connection.
I said something like "I guess the JW service is a bit different from most churches" and he said "To be honest , that was the strangest church meeting that I have been to in 30 years of acting as an executor." I laughed a bit nervously and changed the subject. Most people probably wouldn't be so candid as the solicitor but I guess that would be a fairly typical impression from someone educated attending a JW meeting who wasn't familiar with JW procedures & beliefs.
