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.
