I am not a fan of that approch, it is an embarassment.
But
I worked downtown for over 10 years and that coridor is full of people running to their train at that time to get home. There is a very low chance that anyone would even attempt a stop because in some cases, you miss that train then you are waiting for the next one or you are not getting a seat.
Personally if I saw the guy there I wouldn't care about the train, but that is what makes the supporters nutters I guess.
