Last time I got a memorial invite at the door, they basically slapped the leaflet into my hand, mumbled a quick thankyougoodbye the same moment and turned on their heels. I didn't even have a chance to get a word in. (Not that I wanted to.) What a fine witness! Those were men in their 30s, which you'd expect to be really active in the service.
The only other time I ever see JWs in "service" is at public transport stations. They're usually positioned so that nobody would ever stop for them. They hold up a bunch of magazines tightly to their chest, clipped together to show the title in various languages, definitely not in a way that you would feel invited to actually take one. Most of the time it's elderly immigrant ladies silently staring at the opposite wall with a grumpy face or busy talking amongst themselves. The whole thing is just bizarre and an utterly pointless waste of time.
I mean, I can somehow wrap my head around the door-to-door idea, biblical or not, but whoever claimed that the 1st century Christians stood on street corners passively waiting for people to approach them to find "The Truth"?
They should consider selling kebabs or something. Then at least they'd talk to people.
