For the past four years I've worked in personal banking. I started as a regular customer service representative in the call center and, after a month and a half with no previous banking experience, was promoted to supervisor.
I know my 90's dance music, I know my nasty crafts, and I know personal banking.
Ask me questions about your own personal bank account, disputes, federal regulations (I've read them/get tested on a few of them annually), issues with your bank, bank fees that seem inexplicable, etc etc. Or just general questions about the changing of the industry -- I know other bankers and we talk.
Also, I do have some experience in personal securities as well and can at least direct people to the correct location for services and further information.
US knowledge only (sorry!)
