Espresso maker or Keurig (bring your own K-cups)?

Most locally available coffee in the Caribbean should be local coffee?

I had a guest that wanted to be eco-friendly so I let him use my reusable plastic and metal mesh K-Cups, and he didn’t align them with the arrows, just put them in the Keurig any which way, and poked a bunch of holes in the mesh, ruining them. Not going to put any more of them in the B&B kitchen!
