GRAMMAR POINTS TO REMEMBER
- Should have + Past Participle (The Tool for Criticism): In customer service contexts, you use this to forcefully point out management failures, broken promises, and unfulfilled expectations. It highlights the gap between what was supposed to happen and the terrible reality.
- Example: “You should have hired more staff.” (Meaning: It was your duty as management, but you failed.)
- Must have + Past Participle (The Tool for Deduction): When writing a review, you use this when you don’t know the behind-the-scenes facts, but you can guess them based on the chaos in front of you.
- Example: “They must have overbooked.” (Meaning: I didn’t see their computer system, but the packed waiting room proves it.)
- Can’t have + Past Participle (Negative Deduction): Used to deduce that something was logically impossible, often to expose a lie or a severe lack of quality.
- Example: “The chef can’t have tasted this food.” (Meaning: If he had tasted it, he wouldn’t have served it, so I am 99% sure he didn’t.)
