Sometimes people absolutely amaze me. Seriously.
Iowa State Law states that alcohol sales end at 2a. Now this does vary from state to state, but if you have already been told to leave the bar because its closing time, why would you think that I can continue selling alcohol?
This past summer, I helped more people after 2a who did not realize this was a law than I have had the entire time I have worked at the truck stop. I watch them wander down to the beer section, look through the doors, and very helpfully mention that beer sales stopped at 2a.
The angry ones? Eh. I don't get too worked up over those. And I'd let them in on a little secret: I don't care what they think. I'm just doing my job.
