How to respond shortly to suggestive questions such as:
Do you want to buy this one or this one?
Those are very popular among tradesman and are of manipulative nature. I don't want to explain each time that I don't think such questions are proper, and that none of this option is to be chosen by me, and I don't wish to be asked such questions.
I need a short phrase for such questions, as short as possible, and not too offensive.
