Using a manual tile cutter on porcelain tiles?

[Greenllama]

Hi all, I need to cut one tile down, two straight cuts.

I’ve used my manual tile cutter tool to score the first cut, but apparently no amount of pressure from the lever is snapping that tile.

I don’t really want to buy/rent an electric cutter for just one tile, is there a technique I can try to snap it? Or does anyone know of shops that will cut a tile to size?

Thanks!
