A few things prepared rather than a script to perform — plus the safety basics, questions worth actually asking, and how to end it honestly whichever way it goes.
Which leaves no attention for the actual question — whether you enjoy this person's company. Most people finish a first date knowing how they think it went and not whether they had a good time.
Working through prepared topics reads as exactly that. Four things at most, then follow up on whatever they say — which is also why you won't run out.
Public place, your own transport both ways, one person who knows where you are. It takes two minutes, costs nothing if the evening is lovely, and matters enormously if it isn't.
Meant kindly, and it makes the next message harder for both of you. 'It was really good to meet you' is warm, true, and complete on its own.
