That Is NOT The Same Old Yarn

(The store I work in sells a lot of yarn. We often have multiple batches/shipments of the same colour yarn in our shelves, and we have to double check that both the batch and colour match before we sell it to a customer, to avoid colour differences in the finished product. This happens at the checkout when a customer wants to buy a lot of yarn)

Me: “Now I just have to check the batch numbers real quickly so we are sure you get no colour differences later on.”

Customer: *sighs* “I understand that; we all have our fetishes.”

(I freeze for about half a second from this comment but the rest of the transaction goes as normal. After she leaves:)

Boss: “I really don’t think it means what she think it means.”

Me: “I don’t even want to know.”
