I did this once. I didn't realize it was sushi though.

I was outnof town, training for work. My meals were paid. I decided "That tuna is $20, but I am not paying it so why not.

It was raw.

So I cooked it in the hotel room.

EDIT: Another fun food mishap from that trip, I ordered some expensive pasta from a place I had not been to evet, same logic, "Its $25 but ita not my money.". This was back in 2010 BTW.

I went and picked it up to take back to the hotel. Its a Family Style restaraunt. It was $25 pasta because its meant for like, 4-5 people.
