dodgy...........
what would be the replacement word we'd use here in the U.S. to make the groom burst out laughing?

Flaky, dicey...

I suppose 'Risky', although Im not sure would it carry the same emphasis which is that it could be very very difficult to put up with her. I wouldn't recommend ever talking so directly to a client anyway. I regretted it as soon as i said it as there was a chance she could have taken offence.

EDIT: yea what Vito just said.

As the original poster here I am happy to report the bride that I politely turned away came back, had her fiance call the other day to say she was mailing a deposit and contract.

She apparently was too sheepish to call herself, which I can understand.

We'll see how it plays out.

Awesome, Jeff. Good to get a sales conversion and stick to your guns.
