Actually, it's often not -- it's a declaration of interest and an euphemism for "let's move this thing along for the time being and see where we'll end up".
So, someone who wanted to take things slowly would turn them down, where they might have accepted an invitation for coffee in starbucks. If invitation to bars = drink , bedroom = sex then everyone knows where they stand.

Maybe? It's a negotiation. For example that someone could have counter-suggested a coffee at Starbucks, that's a "you're going too fast" signal. Or said "Sure, but I'll have to run in 10 minutes, I have an appointment to catch", that's a "yes to coffee, no to sex" signal. There is a VERY large variety of ways to signal interest, intentions, etc.
