The things I find out!!!
Do you know where the barber pole came from? In the middle ages the barbers were like surgeons, they pulled teeth and let blood, which was a common cure for pretty much everything, so the pole was for the poor wretch to hold on to, for the veins to pop. The blood was collected in the basin that sat in the lap of the wretch, then when all was done, strips of cloth, or bandages, were used to stop the flow of blood, and then they were taken off and hung on the pole. So the pole had clean white bandages and red bloodied bandages twirling around in the breeze (it was all done outside, as a public spectacle of sots), and that's where the white and red stripes came from. Then, when the pole came from Europe to America, the blue color was added to match the American flag.
Fascinating, isn't it?
