Well, hence...

I don't know if this expression could be correct, because I read somewhere that you can't use hence to start a sentence.

Context: Conversation taken from the dialogue of a British movie released in 1958:

- Ah, of course, scotch on the rocks, I've forgotten.

- Well, hence... take yourt things off. Your coat, I mean.

At first I thought that he says something like "we'll dance" or maybe the name of the girl. But considering that her name is Linda, this word is neither close to hence nor dance. And, certainly they are not going to dance in the flat, just have a drink and talk about some business.

This is the clip of the scene, just in case you think he doesn't say "well, hence..." or that this expression is not idiomatic. Thanks in advance.
