But a hole is an interrupted surface. A straw is a rhombus, which means from any point on a straw, you can travel along the surface to reach any other point.
I don't know where you are getting your definition of hole, but:
hole
həʊl/
noun
By your definition though, only a depression is a hole, if it pokes all the way through, it is no longer a hole but simply part of the shape, I guess? Actually wait, I can still travel along a hole in the ground, so even a depression isn't a hole. So....holes don't exist? Because I can always travel along the surface of every hole I can think of to reach any other point.

a hollow place in a solid body or surface.
So black holes are really giant misnomers to you, I suppose. If I poke through a piece of paper with a pencil it is also not a hole by your definition? I have simply turned the paper into a new shape!
Well, if you really want to get that way, let's consider the fact that we're talking about a real physical straw, not a mathematical form.
In a real physical object, there are no surfaces all-- nothing but variations in the density of wave functions vibrating in a virtual space.
Answer's still zero, then, but for a different reason.
