While we are not into "taking one for the team", we don't insist that everyone we play with is "really attractive". It's all a matter of degree and as long as everyone is happy then no problem. Neither of us see it as doing the other a favour if the potential playmate is "acceptable". To us, acceptable is fine. Unacceptable would be a different matter of course!
There again, this could be one of those "divided by a common language" situations
