Punchy Dan:
I thought the S marked tickets were for jobs e.g Dene were big tonnage was required for like filling in the pit shafts when they were closing . A very low rate .
That’s correct Dan, even some large tonnage coated jobs were Special (low) rate. Much easier to drop the haulage rate to get the job than lower the price of the actual material! 
Probably Tilcon did the same with the M40 contract, Malmic will know, but we on Tilcons own fleet were on mileage so it didn’t affect us. Probably the premium paid to four wheelers was stopped? I never encountered it with RMC, but that may just have been the luck of the draw because I didn’t cart to any really large tonnage jobs of theirs?
