I get sunburned very quickly, and while sitting in a Chic-Fil-A restaurant, near a darkly tinted window, I got a sun burn in less than 15 minutes of high Texas sun.
Tinted.... Glass...
Granted, the UV index was at a 10, and this was during the peak of the day, but still. The right side of my face and right arm (both getting the sunny side) were red when I left.
