Any GOOD contractor should be able to listen to a customers requests and accommodate or explain why it is not possible or wrong. Just because something is done to a code does not mean it is the best way to do it. Example If a code called for 3 inch drain pipe using 4 inch drain pipe is not wrong if code calls for 14 awg wire 12 awg is not wrong. If you can not or do not know how to work with your customer then you should walk away and recommend they find some one else.
With the wire I agree, the drain pipe? Not so much. The same volume of water, in a 3 inch pipe will be deeper than in a 4 inch. (Assuming a drain pipe will rarely be full) Both pipes same slope, the water move same speed. Therefore a smaller volume of water will carry a solid, unless the solid is large enough to rub the top or pipe.
