I thought about the MBB-B thing as well, but maybe this is just playing tricks. Consider this: If somebody add's the addtl B, normally he'd like to stress that 'B is at the same level of MBB hence 100% likelihood he works there. Why would you otherwise? Well, maybe by giving you a 4th option, you're less likely to find out that he actually works at B or B, rather than 'B, if not M?Ok back to .ppt.
