My current gripe is a lack of Shepard's pie.
Aside from the chicken tenders, my favorite meal at school is Shepard's pie. I mean, what's not to love? It's potatoes, corn, and beef in an unholy union that warms one to the core! I got into line for the stuff and waited. Then a lunch lady came out, pointed to some kid in front of me, and said, "Everyone behind this guy needs to get out of line! There's no more!" Note that I had been psyching myself up for this moment since... 2nd period? Oh my god, just get through this final and you can eat nummy! Oh my god, just get through Journalism and you can eat nummy!
So after that, I get into line for a chicken patty, tears in my eyes. Yes, I was so devastated that I cried. They then say that there are no more chicken patties. All they have left are buffalo chicken patties (they're really REALLY spicy) and a single burger. So I get a buffalo chicken patty and plop down at a table.
I guess I should change my gripe to an inability to feed everyone in our school... they never run out of Stromboli or chicken tenders...
