I busk in a pretty small town, like 3-4 times a week. Of course Fridays and Saturdays are my peaks, and also Wednesdays. One problem for me is that in the beginning, people thought it was awesome, cause they had never seen something like that before. But now, after two years of busking, people don't give me as much attention as they did in the beginning.
BUT, i have noticed a big difference in the amount of people coming forward to me and talking about hire me for different events. So i have lost some money in the sense of busking, but i have earned allot more payed gigs. I think it's cause people start recognize me and also know what the get if they hire me.
