Is it normal for a photographer to not reply to an email for over 5 days?
I'm finding it very frustrating and although he's never responded within the same day, it has never taken him this long so I'm starting to think that he doesn't want my business anymore.
We are still going through the enquiry stage and I'm trying to arrange a meet-up with him before confirming him for our wedding. Our email correspondences were going well then I asked whether I could to see a full album when we meet up to which he replied that he design albums individually for couples and does not keep samples album to show. Then he went on to say that I should see more examples of wedding on his website and if I'm still not totally convinced then he may not be the photographer for us and that we need to have complete faith and trust in him to get the best results. I only asked to see a full album more so because all the wedding blogs tell you to and I wanted to check that rest of the 300+ images are going to be good 
I really want to book this photographer so I replied saying that I asked to see a full album only so that we can get a feel of what else to expect on the day and it is by no means to question whether he is the photographer for us (giving him the option to still show me a full wedding) but if it's not possible, then that's not a problem whatsoever... can we still arrange a meet-up?
He's not replied in 5 days but he's very active on Twitter and is tweeting a few times a day! I'm wondering whether I've offended him by asking to see a full album and now he doesn't want to shoot my wedding. If he's just not good at replying to emails on time, then the communication process leading up to the wedding could be frustrating! Please give me some advice and let me know whether it is normal for a photographer to take so long to reply and be offended by a couple asking to see more work.
I know people are going to say just find another TOG but I've had my eyes on this guy for over a year and he's the one. I'm a designer so I'm very particular, his photography/post-processing style is exactly the style I'm after. If I hired anyone else, I'd be showing them his work so I'd prefer to just hire him.
