I am ashamed that I hadn’t reasoned this through given all the rubbish digital services have pulled with “purchases” being lies.
If you’re not going to use the term in a colloquial context while you are in a colloquial setting, then you need to cite what source you are referencing for your definition. Given that you are talking about laws, then you need to recognize that every place defines things differently according to the law. So which law, where?
Being unnecessarily argumentative and snobby while at the same time not meeting your own standards is ridiculous.
