Granite Sink Cut Wrong?

[Daz Gizmo]

We actually asked for drainer grooves on both sides, but were advised otherwise on the day. The sink is not stuck on, it is trapped between the kitchen cabinet and the slab. We asked him not to silicon because we are expecting the section to be factory cut and replaced. 

This is our first kitchen replacement and experience with under mount sink and quartz ...the company seemed great with lots of excellent reviews and we expected quality work and good advice!

it is worth noting that not following the technical drawing this will cause problems with some sink accessories like colanders and chopping boards that can be placed over and in the sinks when not in use.

With regards to the Quartz, was it all cut to size on site then?

Also regarding the sink mounting, I do not think trapping it between the cabinet and the slab is going to be as good as using the supplied fixing clips that clamp tight to the work surface.

Clips should look something like this:
