It's a Conspiracy!

Philip, Sachi, and I were eating lunch in a Chinese restaurant, when suddenly Sachi exclaims, "It's a bunch of gym teachers, comming towards us! And I know two of them! I hope they don't come in here, that would be a bit awkward..."
"Oh no, I know two of them too! Well maybe they're going to Lam's. Or maybe they're going to turn the other way."
"But what if they are going to come here?"
"Well, we're basically done. We could just leave before they even get here."
"But we still have to pay the check."
"Oh, right. But look--they haven't been visable for a long time. They must not be coming here."
"Unless they're trying to get us to think that, but really they're sneaking in the back door to surprise us."
"But how would they know we're here?"
"Do either of you have your school ID cards with you? Maybe the school puts tracking devices in them!"
"Oh that made me think something! What if the school put spy cameras in all the nearby restaurants and stores so they could moniter people skipping class!"
"It would be easier just to have cameras at all the school's doors..."
After a while, we leave, wrapped up in our discusion about whether or not it would be easy to escape from a restaurant without paying the correct amount of money. As I'm walking by Lam's, I suddenly remember about the gym teachers, only to notice that they're right in there, only a few feet away from me! (It's hard to see into the building, as it's brighter outside so there are reflections.) But they can see us perfectly! I hardly register before we pass the window that both the gym teachers who I had this year are waving at me. But, laughing horribly, I manage to say - "The gym teachers! Are in Lam's!"
"Did they see you?"
"They were waving at me!"
We all laugh. "I wonder if this would make a good blog story," one of us says. "It would be even better, " says another, "if we went back and waved to them. But I don't want to..."
"Yes," we all agreed. We aren't brave enough to sacrafice ourselves purposely for the amusment of our friends.
