Update:
So I went back but didn't see him this morning. I thought I'd pop in later before I went home though, just on the off chance - and he was there. I went for it!
I asked for a second (spare) cup to go, wrote my name and number on it and went 'this one is for you' smiled and boosted outa there without looking back.
He called me (which I was extra happy about as I bloody hate texting!) and we chatted for a little bit. He's 25 (and a half). I think he said the cafe was his mums but I'm not sure as we were jumping about on topics. He's studying too, I won't say what incase it makes things too outing.
I was like 'sorry for being so forwards and to the point' but he said he appreciated it and that a woman had never directly asked him out like that before so he was surprised.
I have a holiday due so we've left it loosely at me letting him know when I'm back and free and we will go for lunch or something.
Everything seemed to flow pretty well but the only issue is I can potentially see we are both busy people so I'm not sure how that would work. Or if. Plus I might end up feeling 25 is too young or he may end up feeling I'm too old. But heyho, time will tell.
So that's the good news update guys. I'll keep you posted if we get that lunch date and let you know how it goes :)
