2. I must admit there is some truth in this. One has to know the background of the bidder before deciding to give the award. If awards are made entirely on the basis of the offer, mistakes can be made also. This is because the bidder can get professionals and others to make “cannot be refused” offer which in the end would prove impossible to carry out.
3. It is true that those tasked with evaluating bids would tend to favour known performers rather than totally unknown strangers. The more they know about the bidders the more would their decisions be influenced. It is indeed “whom” you know and not “what” you know.
