Bad News for Black & White Photography

I have a bunch of rolls of film left over from my various travels, and I want to get them developed. I plan on sending some through Snapfish, but Snapfish doesn't do black and white film, which is what I primarily used. I took two rolls over to the local Walgreens, which said they could do it, but they just called me and said that they were unable to process it without potentially ruining the film. Now what do I do??
