Carol puts it up to Ger in Tuesday's Fair City on RTÉ One and the RTÉ Player.
Ger's shop launch is jeopardised when a delivery fails to arrive - and she is furious to discover that the delivery was cancelled.
"A message came in for me," Ger tells Carol, Emma, and Sharon. "And whoever had the phone at that time clicked on cancel. Which of you was it?"
"There's no need for the inquisition," replies Carol. "It was me."
"What?" says Ger.
"You're welcome. Don't mention it," smiles Carol.
Fans can find out what happens next on Tuesday on RTÉ One and the RTÉ Player at 8:00pm.
Fair City airs on RTÉ One and the RTÉ Player on Sundays, Tuesdays, Thursdays, and Fridays.
