My tile lady had a big mouth and complained about frang.???? she told my gf "farang expect quality work and complain too much, but they don't know nothing about tiling" !!! I fired her while she was tiling shower floor unevenly (she filled the shower drain by cement, I was lucky since the drain pipe under the house was not installed yet), after 6 months she was around and stopped by to see my work and admired that done professionally.
