Advertising standards and complaints

In many countries advertising is controlled by law or by rules. In Britain a Code of Advertising Practice says what adverts must be like: they must be honest, fair and decent. If an advert makes a claim, the company must be able to prove it; for example, if an advert says a phone battery lasts a week, tests must show this. If an advert breaks the rules, the authority asks the company to withdraw it. Usually the company agrees; if not, a report is published and the company loses its good name. Opinion: It’s worth checking adverts carefully. It’s not worth telling lies in an advert. (be worth + -ing: it is useful / sensible to do it). Imagined situation: If I wrote an advertising code, I would include rules about honesty. (If + Past Simple, would + infinitive).
