I used to work in a phone shop.

Had someone come in asking why their phone wasn’t working properly. It was visibly scorched and melty. I asked why it looked that way. They said, it came up with an error message saying it had been too cold (not an error message I had heard of before, but I know phones can bring up errors for being too hot, so who knows) and so they had put it under the grill to heat it up.

The grill.

Their first point of call was to cook it.

I said, that’s why their phone wasn’t working, and no it was not covered under the guarantee.
