Courier is usually cleaning in the morning which is long and boring, but then things like reception duties in the afternoon. It's hard work but deffinately worth it and people always drop out so if you went as courier you could tell your area manager when you get there that you really wanted childrens courier and that if any positions are available you would be interested, i've known people switch between job roles in seasons before. The social side is amazing. Everyone is usually always up for a good time and very sociable. It depends on your area too, depending on where you get placed you could be near bars and always out, on other sites you may have to make your own fun but its always a good laugh. Hope this helps.
