Of course if your contracting for "by the foot" thats a different story! Also a $5.00 is a very kind gesture but again in this day and age it's a drop in the bucket and it still falls short under the cirucmstances... Especially referring to Underground BSW, or Underground Drop Burries, when the work is becoming speratic and inconsistant, obviously the larger work volume will always make up for the loss, but when the load of work diminishes that changes the entire senerial!
Good luck to the wolves..........
