Yup, done it twice only...one guy i knew had a crush on me, i liked him too, but he just didnt have the guts to ask me for a drink, so i casually said to him 'so, when are you taking me out for a drink then?'...i married him...
Another guy i liked was working behind a bar, and as i left the pub one evening (i didnt know if he was single or not) i went over to the bar and saId 'you make a love white wine spritzer', next time i went in there he came and sat next to me and bought me a drink.... :)
