OK, I had to stop by HD anyway this evening (where they have cut PVC pipe for me before for numerous non-quilting related projects).
The unofficial policy at the one closest to me is.....if the guy working in the department feels like it, he'll cut it.
I guess I've just always been lucky.
Go figure.
And I go late on weekdays- 7-8PM.
I'm guessing Saturday afternoon would probably would get me a big fat "no way."
