My positive first impression omits how much the demonstrator prepared before the tray-transfer trial. I still enjoyed using it. How should I correct the account so readers can distinguish my work from the help?
What was already set up when you arrived, Mina, and did the demonstrator make any decisions for you after the run began? Those are the useful details behind the general word help.
Tray arrangement, tooling and the saved job were ready. I selected and started it under supervision. They also explained an interrupted transfer before guiding the recovery, which my account barely mentions.
Put those details beside the actions you describe, then keep what you liked about the controls and the run; a supervised visit can be a good experience without demonstrating independent setup or recovery competence.
The original account is corrected, including its opening. It now describes the prepared trial and guided recovery while retaining my positive impressions. Thank you, Toby; the decision-making question exposed more than a general acknowledgement would have.
