How should I finish edging my backsplash?

[Braden Downs]

Hello, we remodeled our kitchen

and overall it turned out great, except for our backsplash.

I thought the installer would apply a thin edge of black grout to the edge, but instead he applied a huge finger width glob and it looks terrible. He also tiled over one of my outlets so I can't attach a plate. I learned a lot about scope of work, communication, and expectations......

I need to go back and fix the edges of the backsplash on the open edges on the wall and around the window (under the cabinets will be fine).

Should I:

A) Remove the black grout on the edges and install pencil trim?

B) Remove the edge tile pieces and re install new tile pieces with metal trim?

C) Tape my tile and just paint over the grout?

D) Find the guy who installed my tile and punch him in the face?
