my husband works road construction and they don't usually get to go to the bathroom, and the flaggers.... they are there for the duration....lunches is the ONLY time they get off the site! I wish when ppl are stuck in traffic and getting upset that they would remember that those ppl are out there in the heat, probably haven't gotten to get anything to drink or use the bathroom while ppl are in their air conditioned cars cussing at the workers!! Next time your stuck in the traffic... Offer them a cold water!!!!
