A guy goes into a bar and sits to have a drink. He's had a rough day, some shit went down at home and I think he lost his job. An undercover cop comes and solicits him to pay her for sex. He declines. She leaves, and returns a while later. She repeats her offer, he declines again. She leaves again and returns a final time, continuing to hound him. Just to get her to shut up, he asks "how much?" The cops come him and cuff him and the man is placed under arrest for attempting to pay someone for sex.
That came from a news article a teacher from high school showed me. That is entrapment. That is also nothing like the situation discussed above.
I worked at 7-11 this summer. I was shopped once. This includes a minor coming in and attempting to purchase alcohol or tobacco. If I fail to ask for identification, or receive it and sell anyway, the sheriff comes in and arrests me. This situation would not be unfair, because I know that I am not supposed to sell to minors, regardless of whether this person actually wanted what they were buying.
By the way, I passed.
