My answer to this question is much he same as to the on that you asked about admin work. i.e. that it largely depends upon the level of dyspraxia (which can be anywhere from very mild to extremely severe).
For example, I've supervised a team of people working on a fairly new housing development in Didcot. We were going from door to door, asking householders loads of questions about their use of public transport and cycle routes etc (on behalf of the site developers, who had an obligation to do so periodically under the terms of their planning consent).
One of the guys on the team has dyspraxia. He's a lovely guy, highly intelligent (with a degree in mathematics) and with a far better work ethic than anyone else that I've worked with on that job. However he wasn't well-suited to the task, as he lacked the ability to handle face-to-face contact with strangers well and was unable to pick up on non-verbal communication signals (e.g. whether someone was happy to speak to him or whether they just wanted to tell him to F off). He simply wasn't a 'people person' at all. He was also very poor at keeping all of his paperwork neat and tidy and recording data in the way that was required. If you asked me if that particular guy with dyspraxia was suitable for a reception job then, regrettably, my answer would most definitely have to be a great big "No".
So you need to ask yourself how your dyspraxia exhibits itself to others. If it makes you seem 'decidedly odd', as the guy I'm referring to almost certainly did when people answered their doors to him, then reception work isn't for you. If you can't fill in forms (such as telephone messages) clearly and then keep them properly organised, as this guy seemed to be unable to do, then again, reception work isn't for you. However if your dyspraxia is less severe, or presents itself to the world in a far different way, you might actually be the ideal candidate for such a post!
