"I'm just going for one innocent drink..."
Any range of complimentary white lies that might improve the vibe and lead to a better punt.
I generally don't disclose what I do or where I live, so I've found it easier to have another career that I can talk about rather than have to think of new shit every time. In the early days I said I was a fireman which seemed to have a positive effect.
I told a reg some years ago it was my birthday and I ended up banging her in the ass for free (it was normally an extra). Happy days. Some time later in another punt we were chatting and she randomly asked me my star sign. I answered that honestly, and she follows up with "Oh I thought you were XXX". Made me think that some SPs do pay attention.
