A Long Job...

"Well lads, that's the first 5 metres done. Only another 145 to go on this lower roof, and then we can move on to the top roof."
In reality there was another team working on the top roof.
Large shopping centres always seem to have a flat or flattish roof.  This is a problem  when a large amount of snow arrives and your roof is suddenly holding up all those extra tons! I reckon these guys have several weeks of employment on the roof of this well-known sSwedish furniture store.
