Of course there are venues I won't play, but then I'm probably not going to be asked anyway - dance clubs, bars, etc. ...

If I'm playing background in a CC or restaurant a lot of what I play is for me ... in most cases, if I am going to like it the audience - who ever might be listening - will like it as well ...
When playing a Senior Housing or NH venue, definitely I am playing for the audience ...
That goes for private parties as well ...
