Ouch. D: I'm pleased I've never been burned that badly, it must have been awful for you all. <3
The worst I've ever had was one from work... I work in a restaurant, and the counter is a hot counter, the type where the food is on top, and it's served plate by plate by the worker rather than the chef making the meals seperately. I.e, the customer chooses what they want from what's on the counter, then the worker plates it up for them. Underneath the counter is "hot holding", where the next round of food is kept hot before it's ready to take out. It's essentially an oven.
One day it got very busy at work, so naturally, I was moving quickly, and despite usually being cautious with the oven - okay, I'm scared of it - I was being a bit careless. When going to grab this tray of baked potatoes from underneath the counter, I didn't think about the actual rack the tray was on, and managed to burn my forearm and hand. D: It hurt but I got the cream and whatnot on it quickly, so it was okay. No scarring, either. o.o
I tend to get splashes of hot water all over myself now and again but it's not usually bad.
