Hello Nickle
Welcome to the Coffee Forums!
I think your idea of offering fax and copy services is a great one.
Since your coffee shop is in a seasonal resort area, I'd bet that there are lots of people who would take advantage of your services to make a quick copy or send a fax while they're on vacation. It isn't easy to find those services on weekends or evenings when the local library or post office is closed. I can picture people stopping in for a cup of coffee and sending a fax while they're there. I wouldn't predict that you'd do a huge amount of copy or fax business, but just having it available to your customers wouldn't cost much on your end, since you probably already have a fax machine and copier there for your own use. I can't imagine it becoming a problem. It's not like you'd be making a hundred copies for someone....that's what the office supply stores are for.
It will be interesting to read what everyone else thinks about your idea.
