Did i make a mistake or was i stupid?

I am a 24 yr old highclass prostitute(cos i have no one) & last night i was with a hot client who was so aroused he didnt wanna wait.i told him the usual "money in my hand first,then my back on bed" but he assured me payment and he looked realy rich so i broke the major rule and gave in,only for him to later reduce my pay and i could do nothing as he left.was i stupid or i just made a mistake?
