Plump Plumber

I think I'm a little closer to understanding why plumbers drive merz and engineers drive vios. I had a leaking pipe (actually its just the nut) under the sink and called a plumber to ask for pricing. He said in ah beng style "$50 for repair... change part then $150".. and i replied "repair can liao". Dunno why but i expected him to come and say 100% need change part de. And as expected, his first words were "waaa jialat this one need change part" ... At that point, I just felt like a vegetable head. But too tired to do anything, but get the leak patched. And so, we pay for our mistakes, and next time, I am doing my own plumbing, that is if I am not tired again...
