Ha ha - typical!!
On one of my recent excusrions to Edinburgh - they were pointing pathing flags on one corner of George street - 1 guy pointing , 1 guy mixing a bucket of cement, 1 guy brushing up , 1 guy drinking a cuppa and watching the rest. I walked past them at 10:00am and later on in the day when walking back to hotel (about 2pm ) they had managed to point 2 flags! 2 Flags!!! I did the whole of my patio in 1 afternoon by myself!
