In my experience, in the white collar world, corporates really don’t think twice about paying for this stuff.* In fact, they’d really prefer that you just use the company card instead of blasting stupid bullshit like this on social or making yourself sick. This person’s boss probably thinks they’re fucking insane.
*If you’re blue collar, you can usually get fucked. If they do much as buy you a Costco hotdog and soda, they’re going to complain and hold it over your head. Little Caeser’s hot-n-ready pizza is the definition of spoiling your workforce in that world.
If charging dinner to the company is going to tank your P&L, you've got much bigger things to worry about. And no, they ain't going to promote you because you saved them $30.
Generally I find the people who go all out (not overboard) on expenses get promoted before people who don’t. Shows a level of confidence that most management likes.
I saw a YouTube video of a guy cooking a steak by wrapping it in aluminum foil and putting the hotel iron on top. But an iron gets a lot hotter than that warming plate, plus beef is less bad to eat undercooked.
This would probably work fine, it might be a bit slow, but a coffee pot gets plenty hot to cook chicken. My main concern would be the lack of fluid increases the chances that pot breaks.
The hot plate 100% has a safety switch that turns it off at a couple degrees above boiling. So it won’t break but it also won’t sufficiently cook the chicken with pieces this large…
"Chunky" chicken soup in a can just costs a couple dollars, you could try heating that in a coffee pot. Add some fresh cherry tomatoes and canned fruit and you have a good meal.
