Context: They asked us to come off rudely , which was needless as we were hardly going to argue . Then a third woman arrived , though she was a real copper and treated us really respectfully and politely . She informed us that she 'd have to take our names because she had stopped us , just for formalities . So we did so , with a laugh and joke , before I said , ' So , common ? '

Question: What leads the speaker to refer to the third officer as a ' real copper ' ?
Options:
0. The speaker believes that real cops hold themselves to a certain standard of behavior
1. The first two cops were impostors and if the third had n't shown up there would have been trouble
2. The first two people that dealt with the speaker were firefighters , not police officers
3. None of the above choices .
Answer: 0
