I enjoyed watching your work but I certainly hope this is not the case where your from. Here in Canada(Quebec in my case)I have been running festivals for 7 years and they have always been very friendly, cheap to attend, lots of food, no plastic sales at the concession stands, only hand made items. And last I would not book a musician if he/she expected to be apart from the audience. It is expected that the musician will have time to walk around and talk to the paying customers.
