If he's waiting too long to make a move it's because?

[JaneMarple]

I work in a big building and in the afternoon I always take a break and go downstairs for a coffee. There's a man who works for another company taking his break at the same spot. A couple of months ago we started chit chatting and now it's become our routine, we've even become confidents. In our conversations he told me each day he's looking forward to our meetings, I put a smile on his face, I brighten his afternoons..blablabla.

Shouldn't he by now have talked about taking these meetings <outside> working hours!

So ladies, how long would you be standing by, waiting for a man to build enough confidence to ask you out?
