Had a house today that was a "Class A" Home Handyman special. Image reflects a bar sink drain (yes, I know there is no P-trap ... let me finish

). The drain includes the flexible product that is okay for "home handyman temp" use and the horizontal line goes through the wall and connects (about 4') to the drain in the adjacent bath sink at the appropriate location above the P-trap. Slope is okay all the way.
Picture a kitchen dual-sink drain where one drain stem comes down and then routes horizontally to the adjacent sink drain stem & P-trap.
With that thought in mine I have two questions:
1) Would you approve the current arrangement going from the bar sink to the bath sink?
2) Would you approve the flexible connection?
I'm afraid I'll be writing for a while on this report. It was a pre-listing inspection. Most of the modifications were done by the prior owner from what I understand. AND ... current owner is an agent.
Gonna be interesting to say the least.
