however, my statement about entitlements of the performer being non existant along with the listener having no obligation to pay the performer because they stayed for some amount of time, was made on an moral level. i also believe it is a morally 'good' thing to compensate the performer if they provide you with entertainment, i just do not believe there is any obligation placed on you to do this by the performer. like you say, it is for me alone as the listener to decide. i objected to the use of the word 'owe' in the advice, basically.
hopefully that's a bit clearer...
