Would you ask for help?

[GoodwillRef]

Twins manager Ron Gardenhire questions HP umpire Larry Vanover that the ball hit is batter's foot, he was put out by the 1st basemen, he is asking very nicely. He then asked Vanover if he would ask 3rd base umpire Charlie Reliford for help and Vanover tells him 'NO" and then he throws his hat and goes crazy and gets thrown out of the game. Why do MLB umpires refuse to ask for help from crewmates? Replay shows that the ball did hit his foot and should had been a fould ball. Would you ask the 3rd base umpire for help on this play? I would.
