DS2 was standing with his back to a portable heater in a shop. I've now noticed the back has melted.
Am I right to think this heater was unsafe? I'm in two minds. On one hand it was a heater and thus hot but on the other, it shouldn't be hot enough to melt clothing nor put in a position it could do so. Especially in a public place like a shop.
There were no warning signs and no staff suggested he move.
