"And I'll take these, please."
"Did you pay for your treatment already?"
"Yes."
"Credit card or cash?"
"It was a gift certificate."
"That was thoughtful. I don't see a gift certificate here, though."
"It was phoned in yesterday, probably by credit card."
"Okay, let me see... Hey, Cynthia? Cynthia? Sorry, she's always busy... Cynthia! Where's the roster for this morning's treatments?"
"--"
"Well, why wasn't it near the computer?"
"--"
"This gentleman wants to add these items to his gift certificate."
"Actually, I can pay for those separately."
"You sure?"
"Yes."
"Okay. Let me subtract the price of the items from the gift certificate."
"It was a phoned in credit card payment, not necessarily a gift certificate."
"Oh, that's right. Sorry about that."
"No problem."
"Cynthia, how do... Cynthia! Damnit. Sorry. She always runs off."
"That's okay."
"Cynthia, how do I add these items to the phoned in credit card payment?"
"--"
"I wanted to pay for these items with cash."
"Oh, that's right. Sorry about that. That'll be $4.75."
"Thanks."
"No, thank you. And I hope you enjoyed your relaxing stay."
