Re preparing for a first date: that's pretty accurate. You make sure it's a public place, and that you know how to get home from there easily, even if incapacitated, and you tell a trusted person where you are going and who with and what time you want them to check on you. That's just standard. The taking a photo of the guy and his reg plate is not a thing I've heard of before, but I sure as shit will be doing it to any lad who turns up in his own car to take my daughter out now I've seen the suggestion.

That's a good idea too.
