I believe it was more the case that the shop assistant believed that ratings on games at the time were like those on movies, enforcable by the law, which was not the case.
Still, it was about 14 years ago now so I think I have finally let go of the Thief debacle.
As a business owner its his choice if he sells it to you or not. And whilst you may think "oh hes being a ratings Nazi", maybe he just wanted to do his job well and uphold a standard for his shop. Either way he had every right to do so, as a minor trying to buy something you know is not meant for you. Id say him being the adult in the situation, did you a favor. Or at least allowed him to go home at night happy he wasnt selling to minors, moral compass` and what not.

PEGI becomes UK law today
PEGI age classification for games becomes law in the UK today, making it illegal for retailers to sell games to anyone under age.
Although it feels as though it’s been around for ages, PEGI is now officially UK law from today, enforcing the standard on retailers everywhere.
The PEGI age classification system completely replaces the classic BBFC ratings, which will no longer be used.
PEGI also comes with harsh penalties for anyone found to be selling games to anyone under age, such as a £5,000 fine and up to six years in prison.
Culture minister Ed Vaizey chipped in with his own thoughts on the PEGI standard: “The UK has one of the most dynamic and innovative video games industries in the world, and the games they produce not only entertain millions, but can also educate and foster creativity.
“Today’s simplification of the ratings system benefits both industry and consumers and will help ensure that the millions of games sold in the UK each year are being played by the audiences they were intended for.”
