Exactly. I don't know why so many msians get tricked into this stupid lie. This morning A/C guy came to clear the A/C drainage pipe because they didn't do it properly the last time, then want to check A/C gas pressure. I told them off "what for you check A/C pressure? Every time you check the gas will escape bit by bit. You're the one causing the gas leak." The guy senyap only.

If it's because I'm a cheapskate pay for cheap A/C salesman never, but even those I pay DOUBLE the labor charge also pull the same nonsense. Damn jibai.

not all
there are still honest one but they're hard to find

rich people know where they are but they won't tell you where
