I was reading this thinking he needs some 'Yes and...' improv goodness and then you said it. I think it's a balancing act you can't always agree with everyone otherwise you'll be back to chode square one where you appear to be agreeing just to get them in the sack but then again if you disagree with everything you'll look like a tit.

I think it's tact and judging the situation properly so there's no magic bullet answer but you realized that you'd gone too far in saying it's shit and I think you were right in thinking you should have said you prefer someplace else.

It's made me think more about not agreeing but offering a different view point instead of smashing their views to bits.
