On some of the bigger projects that have 80-100 men working. I tried testing some people there to see if they listen to yah. First I tryed proper english, seemed like their minds would wonder, preoccupied, get bored fast and short span of attention. So the next time I was talking to them, I put in all the 4 letter adjectives, funny how all eyes were on me waiting for their chance to reply with all the 4 letter adjectives.
