You didn't have time to put the pan in the sink and let some water sit in it?
But yeah, your roommate is retarded.
We have 6 pans, it's not like he needed to use that exact one.
Plus we have a high pressure sprayer in the sink and it takes literally 15 seconds to clean dried up bacon grease off a pan. Especially that one since it was teflon coated. It's not fucking rocket science.
