  In a recent preprint, Lai and Rohatgi compute the generating functions of
lozenge tilings of "quartered hexagons with dents" by applying the method of
"graphical condensation". The purpose of this note is to exhibit how (a
generalization of) Theorems 2.1 and 2.2 in Lai and Rohatgi's preprint can be
achieved by the Lindstr\"om--Gessel--Viennot method of non--intersecting
lattice paths and a certain determinant evaluation.
