Straw said he feels uncomfortable talking with someone whose face is covered, saying the veil could be seen "as a visible statement of separation and difference."I'm not sure about that explanation, but I'd be uncomfortable talking to someone whose face was covered. If they want to talk to me then they have to live with the fact that I have some prerequisites, including seeing the other person's face. I agree with Straw that there's a world of difference between the headscarf and a veil.
However, if a woman doesn't want to uncover her face then that's her choice. She just has to accept that many people will not want to deal with her. Shopkeeprs or whomever may not want veiled women in their shops, which is their choice.
