Police and beer

"Good evening, Mr. Driver. This is a road control. Your papers please." "Right here in the middle of the road?" "What do you mean?" "I mean, right here in the middle of the road, with all these cars whizzing by? Why can't you stop me in that parking lot, or on that side street?" "Because I am from the police, and I can stop you wherever I want." "But it's not very safe." "Well, as you can see, I have a reflective vest." "But I don't." "Then you should buy one. Are you willing to take a sobriety test?" "Yes, of course." "Hmm, 0.0, everything seems to be in order." "Okay, so where is my free nonalcoholic beer?" "Can you believe this?" the officer says to his partner. "Now he's demanding a reward for not being drunk. That ad campaign ended last week." "Fine, I didn't really want it anyway. You were giving out Staropramen, and everyone knows that Birell and Clausthaler are the only two decent non-alco beers." [Czech Republic sober non-alcoholic advertising Plzeňský Prazdroj InBev]
