@lm - welcome to the board! The same thing happened to me on a business trip. Only I forgot my jacket but had my books. One of the elders in the hall approach me and I told him I was an elder visiting from another state. He told me the hall wasn't friendly (he had just moved there) and spoke with me both before and after. The rest ignored me. And I even commented several times!! I was really shocked. What if I had been an interested person. Man, they didn't even do "lovebombing" correctly.
One time I was on vacation and went to the memorial at another hall. I was completely ignored except for another visiting JW. I was a young MS at the time but still was thinking that this congo was seriously jacked up. Now I know they all are!!
007 - the whole badge thing is insane. I never wore a badge unless I was an attendant or working in some function that required one. Now, I make it a point of never even bothering filling one out. I would say that at least 33% of the folks don't have one. That guy was an a-hole
