They're a little suspicious.

The couple turns to look at you and the lady of the pair says, "We're just looking at the moment. I'll bring something over when we find what we are looking for."
You smile politely and then pretend that you are busy looking through the store's computer. The couple starts to have a look at the many stands of bras and underwear giving you sometime to wait. It soon becomes apparent that you have no idea how to work the till if they decide to buy something.

As they continue to browse you look down and notice the discarded pile of clothes from Jade and the UPS man. You panic for a brief second as you look up and see the pair coming towards you carrying some items. You quickly push the clothing under the service counter so the shoppers won't be able see it. The lady arrives in front of you and puts a matching set of bra and panties together with some knickers she pick out of the three for ten dollars bin.

You are thinking about how you are going to charge her for the items when you hear from the back of the store an audible "ohh!" that you know is certain to be Jade building towards an orgasm. The lady gives you a quizzical look and starts to look through her handbag for her purse.
"That's just my boss," you say to cover for the previous moan.
The lady smiles, seemingly having accepted your explanation and presents you with a fifty-dollar note for the intimates. Having never been shown how to work the computer you grab a calculator from beneath the counter and add up the prices which come to just under forty dollars. You take the money and realize that you are going to have to open the cash draw. It is locked and there is no key present.

"I won't be a second. I just have to get the till keys off my boss," you say to the girl.
The women nods and you head out back to the cubicle Jade and the delivery guy is in. You open the door slightly and look in. Jade is pinned up against the back wall with her legs wrapped tightly around the guy's waist. She notices you peering in.
"I need to get into the till," you say to Jade.
"Shit the keys are in my pants. You'll have to pull the till out. There is a latch on the bottom of the draw ant the back," Jade tells you in a very husky voice.
You close the change room door and head back out from. As you are leaving you hear Jade call out to you "THANK YOU".

"The computer system is down," you explain to the shopper as you manhandle the till getting it open. You place her money inside and count out the change for her. "I can't print you out a receipt for you either unfortunately. If you wanted to bring the clothing tags in next time we could have one done for you then."
"That wont be necessary," she replies to you.

You then collect the items from the counter and place them with in one of the stores carry bags. The lady is organizing her change when you hear another "urggh," this time coming from the delivery guy.
"What are those noises?" the lady asks you.
"Oh were are just having some work done out the back of the store. My boss is there helping the guy," you make up for her benefit.

You aren't sure she believed you this time as she collects her belongings and walks out the shop with the man whispering to each other. In perfect timing, just as they leave the shop and walk away you hear another grunt and a loud scream coming from out back signaling the climaxes from Jade and the UPS man.
