007 I had a similar experience at our bethel. My wife and I took a sister to bethel to meet up with her bethelite friend, I was working that day so I didn't have a suit on but knowing how strict they are about dress I told the guy on reception I was happy to sit outside in the car. He was really cool with the fact that I was wearing jeans and just told me to take a seat in the reception.
I was just sitting in reception reading a watchtower and 3 sisters in a row approached and asked me what I was doing! The 3rd one said 'you have to understand this is bethel and we can't just have anyone walking around here!'
At that point my wife got mad and told the sister that our contributions were keeping bethel running and she shouldn't be so judgemental. There's nothing 'happy' about that place.
