The big difference is that if you are not happy with what a car dealer offers, to can check whether another one can make a better offer.
In the case at and, there is no alternative. You need to take what the car dealer offers you or have not car at all.
That is not true for May. She is a lousy negotiator. Negotiation is an art. The guys at ACAS have arbitrators with arbitration diplomas. It is knowing how to drive a hard bargain between, say, a rail union with striking members holding out for specific conditions against the bosses on behalf of the government 'refusing to budge'.
A good negotiator will hammer out a deal that is win-win for both sides.
May has no negotiating skill at all. She has sold the UK down the river (thank goodness for Gina Miller forcing her to have it approved by parliament first). She has brought about a 'lose-win' deal in the EU's favour. Of course they have approved it. What's not to approve? She has conceded at every possible juncture. She has made the fatal mistake of wanting to be liked. She has shown herself to be acquiescent and amenable when toughness and vision was needed. To try to cover up her deficient negotiations - if we can even call it that; 'surrender' is a better word - she makes matters worse by using dog-whistle racism in her appeal to the British public ('no more queue-jumping by EU nationals') and blatant lies.
Someone needs to give her Sun Tzu, The Art of War for Christmas. She sees herself as a latter day 'Iron Lady' Thatcher, when in reality May is a pushover five-quid slut in curlers who'll say, 'OK, I'll do it for a quid'.
