In and Out
Vegeta confidently shoved it in only to have it pop right back out again.
"Vegeta?" Goku asked.
"Just wait a second," he answered. Again, he pushed it in. Again, it came back out.
"Problem?" Goku asked, trying to conceal the smile that would only irk the other Saiyan.
"No!" he snapped and shoved it in even harder. It slid out.
"Need help?" Goku offered with a sigh, his patience nearly at its limit.
"Hang on!" Vegeta took a deep breath to control his anger, pulled it straight, aimed, and shoved again. It seemed to want to stay in, but then popped back out once more.
"Really, Vegeta, can I just..." He reached for it, but Vegeta batted his hand away.
"I can handle this, Kakarot!" he yelled in Goku's face.
With god-like speed, Goku snatched the bill from Vegeta's hand. He carefully smoothed the wrinkles out against the edge of the pop machine and lightly pushed it into the slot where it was immediately reeled in and accepted.
