It's a joke

Steve actually laughs a little as Kirsty looks at the pair of them in shock. "Sorry, it's a joke," Steve tells her, as Dave wanders over to join the pair of them.

"Technically if you started streaking all over the place we'd have to take you in," Dave explains, "but it's not like you'll get in trouble for accidentally dropping your skirt like that, just keep it done up."

With her hands holding her skirt tight around her waist she doesn't have a free hand to hold her shirt closed and she's very aware that both men are watching her cleavage with interest. "Thanks," she mutters, not really meaning it, and glancing at the door to the back room. "I need to go and fix this."

"Sure, no problem." Dave tells her with a smile, "is there someone to run the shop for you?"

"Not for another half hour," Kirsty replies, suddenly a little despondent.

Steve smiles. "Don't worry, we'll wait out here for you, make sure no one comes in."

Kirsty nods to the two of them and begins to make her way towards the door to the back room.
