Tom Gresham had a story a few months ago about a guy who went to Home Depot to buy some construction material for his gun-parts related business, and his credit application was rejected. They told him it was because they won't finance any gun-related business. He followed it up the management chain, and found out it wasn't a Home Depot policy, it was a Citibank policy, the actual bank that lends the money. He went public with this, and got Citi to make some public apologies and changes.
