There is no bid/ask as you know and that applies to ALL. What can happen is this:
Sometimes a broker will tell a buyer or seller what the "bid" is. This bid is NOT a true bid as we know. It is simply the "bid" of their clients.
For instance if I ask Scottrade what the PHOT bid is they may say .043. All this means is that the highest open order within Scottrade is at .043. They never know what the rest of the worlds orders are for.
Hope this clarifies the bid/ask scenario you presented...
