Don't look a gift horse in the mouth.
Beggars can't be choosers.
I'm always surprised at those that ask for something free, but when you offer them the free item they then state no I don't want that. It all comes down to how badly does someone want something. If they are hungry enough, then they will take the item. I have seen people take trash, item out of dumpster, and make it work. Since most folks only use the straight stitch when sewing, a vintage straight stitch machine that can stitch through heavy material is all that is needed to do the job.
