As we learned from the aftermath of the last major meltdown, banks do a lot of deals that require more than just a Bloomberg terminal. If anything, deals like ( http://www.independent.co.uk/news/business/news/goldman-bet-... ) require more physical presence, as nobody wants to leave a paper trail.
Can you elaborate on this? If you bought something from me then I think you paid too much and you think that you paid too little. That's, like, how buying things works. I wouldn't sell it to you if I thought you were paying too little and you wouldn't buy it from me if you thought you were paying too much.
