At Camp Half-Blood, there wasn't much descretion on what a new camper was told by their guide after meeting with Chiron. As long as they got the basic idea of the camp, everything would be fine. Cabins there, don't go into the forest alone, show up when you're supposed to for activities and meals, and Capture the Flag's on friday.
Simple, right?
That's what you'think.
in reality, there were actually a few more little things that had to be covered.
Like how you shouldn't fight Clarisse (or any of the Ares campers, really) until you were sure you knew how to use your weapen.
Or how you shouldn't bring live or dead sea creatures into the vicinity of Percy or the Poseidon cabin unless you wanted to run for your life.
Or how you shouldn't insult Nico in any way unless you wanted a legion of skeletons and Will chasing after you. Because even though he was pretty laid back, Will Solace did get mad when Nico broke his "no Underworld-y stuff" rule. Or when someone (aka his boyfriend) got insulted.
Or how Blackjack was Percy's horse, no ifs, ands, or buts about it.
Or...
Well, you get he idea.
Although there was always one or two rules that gt skipped, there was, however, one rule that was never, eer, ignored...
It was a beautiful summer day, and Camp Half-Blood was bustling with activity. THe 5th Cohort was visiting (Will was screaming something about how unhealthy all the Kool-Aid Dakota had brought was unhealthy, while Pollux and Dakota simply kept on chugging), the campers were going around doing their usual activities, Percy and Nico were arguing over sword fighting techniques...
Well, that was what was happening. Until Christ Rodriguez and Cecil Markowitz got into an argument over burgers vs burritos and Chris mentioned that at least "burritos aren't as fatty as a McDonald's burger".
And halfway across camp, two minutes later, a fuming Nico was screaming bloody murder and it took the efforts of Percy, Jason, Piper, Hazel, and Will to keep him from going over ad sending Chris to the Fields of Punishment.
Thus the rule of "Don't criticize McDonald's-anywhere" was made, in hopes of letting everyone stay alive.
