Credit scores are strange animals, and they don't make sense to me at all. I don't understand how a college kid with zero credit history and no job, can get a great card from a major bank, and a retired Texas oil tycoon with a billion in assets can't qualify for a 99c store credit account sometimes. I would think it would make more sense to assess whether the borrower has something to lose or not, by handling the card responsibly or not.
As for the OP's question, I'm more comfortable with a bank I can walk into, but honestly with today's banking environment, there isn't much chance of someone you know in the branch being able to do anything special for you anymore. It used to be that the branch manager could waive fees, or raise your limit, or even approve a questionable application if they knew you. But not so much anymore. I hate phone calls, but if I didn't hate phone calls, I'd probably not care if I had the ability to go to a local branch or not.
