I agree, unless he was very inexperienced. And I still don't get why it took 20 mins in that area. And paperwork, what paperwork? Putting a tick in a box? Tacos etc are done before and after aren't they? Eating a bacon butty, reading the paper, scratching his arse, dragging the job out, something wrong with the truck, phoning the depot because a bin is unusually heavy, checking social media, interating with a drunk, any of those things I might believe. But paperwork? Still I guess it must all be so on cctv, and whether it is usual for the job it to take that long or comparison to other days.
But if you found a body in a bin why wouldn't you call the police?
20 mins in mentioned below, it is also on the timelines on the earlier threads. Though I'm not sure how accurate that it.

I think that the times were unclear quite often, and maybe Midsummer, who made the timelines on here, had got 4 am from one source and 4.20 am from another source, so he was conjecturing why the binman was in the horseshoe for 20 minutes. But we don't have any solid evidence he was there for 20 minutes (Nicola said around 4 minutes, which sounds more reasonable) let alone doing paperwork for 20 minutes.
