Own nothing, ('cept the guy behind the counter, pity him,) I think I made Pete's Pizza up but if I didn't well, "one two, better not sue." (Simpsons quote, that's sorta appropriate, right?)

Daniel and Sam had been found together and after coercing them to come along Jack had gotten sulky, which had in turn frustrated Daniel, leaving only Sam in something resembling good mood.
None of them could remember what had made them think this was a good idea. The force of Jack's personality is often enough to make one change one's mind, but since Jack's personality was sulky at the moment . . . what the author is trying to establish is that they were all in very bad moods. Has she got that across? Good, on with the narrative.
The car ride to Jack's favorite pizza place was uneventful, or uneventful enough to be skipped over.
"It is closed, O'Neill," Teal'c stated.
"What?"
"The restaurant at which you wanted to acquire pizza is closed."
"Aw, must be a Sunday." Jack leaned around Teal'c to peer out the passenger window.
"It is indeed."
"Why didn't you say anything?" Jack demanded.
"You did not ask."
"You expect me to keep track of the days when I'm--"
"Would you two . . ." Sam and Daniel began at the same time and then turned to glare at each other, they were becoming increasingly antagonistic
"Alright, alright," Jack said. "We'll go to 'Pete's'."
"Jack," Daniel whined. "Their pizza tastes like--"
"We're going to 'Pete's'!"
Daniel sighed and slid further down into his seat.
Jack pulled away from the curb and rejoined the flow of traffic. Sam tried repeatedly to start conversation but either Jack refused to talk or Daniel managed to sabotage it. Desperation had forced her to the point where she was almost willing to listen to fishing stories by the time they reached 'Pete's Pizza.'
Daniel was smiling grimly to himself, Sam was restraining herself from hitting him (they were annoying each other, mood swings, remember?) and Teal'c was as impervious as ever.
"All right big guy," Jack said. "It's up to you."
Teal'c exited the car and made his way toward the restaurant.
"You sure you should trust him to get the pizza?" Daniel asked.
"It's just pizza, how badly could he screw it up?"
Daniel and Sam had added their pocket change to the total amount to bring it to a whopping $74.32 and Daniel was starting to have second thoughts about entrusting it to Teal'c for food, Teal'c's taste being rather questionable.
"Do you really need to ask that?" Daniel demanded.
"I'd trust the guy with my life, I think he can handle Pizza," Jack snapped.
"They're two very different things."
"I agree with Jack," Sam said. "What's the worst he could do? Besides, we can't leave the car."
"Trust me," Daniel said. "I know. I'm just saying maybe we should have given him instructions or something."
"He'll be fine Daniel," Jack insisted.
Meanwhile Teal'c was stuck talking to one of the most meticulous people in the service of 'Pete's Pizza'.
"Do you want anything to drink with that?"
"No."
"You sure you've got everything?"
"Yes."
"Alright, say it one more time."
Teal'c glared and began the list again, before he could get halfway through, "Are these larges or mediums?"
"Large."
Even though the man behind the counter was only trying to be helpful, he was slowly and surely incurring Teal'c's wrath. Trying to remain patient Teal'c started over at the beginning.
"Did you start over or do you want two of everything you just said?"
With an exasperated sigh Teal'c decided simply to ask for nine plain pizzas.
"You do realize you were getting eight before right?" the man behind the counter asked.
"Yes."
"But you want nine now?"
"Yes."
"Okay, okay, just checking. They should be done in about ten minutes," he said and ran to the kitchen.
Teal'c sat at the bench provided and carefully watched the man's every move carefully, which only caused the employee to become even more flustered and clumsy so that everything took even longer. Teal'c was unaware of this though and so it was another thirty minutes until he returned to the car.
