Working in a tool shop

A young girl took a job in a tool shop and was quite happy with it selling saws hammers and such, when a bloke came in and asked for a bastard file.

She went crying to the manager saying a man had sworn at her.

The manager explained that the big files on the right were called bastard files, and so she went back to work

Another guy came in and asked for a file she smiles and says "do you want a big bastard?"

He said "no thanks

Spoiler:

I want one of those little down there."
