Imagine if that inner bag had gotten a hole! I know UPS tends to be rough with packages so I wouldn't doubt that them tossing the box around probably had a hand in that mess but imagine the spread of lye if that bag had gotten a hole. The conveyor belts that move the package, the people loading the trucks, the drivers, neighborhood pets...all at risk for lye contact. Heck, even trasfer to other packages from the UPS truck, that's crazy! BB is lucky that you are the only one who ended up getting the small burn that you did.
