I don't know the context of the statement. But I can take a guess :
If Agent Foster was really in a hurry to reach Andrews, it could mean that he was in so much of a hurry that he did not bother to put his "tie bar". Being an agent, I think his suit would generally require a tie and a tie-clip (also called a tie-bar) to go along with it.
In the context, this might be one of the appropriate deductions, though I might be wrong.
