I imagine Cronan would stand out at Pizza parties, since he likes pineapple on his pizza. Heck he'd be thrilled if it has EXTRA pineapple.
Also I'm convinced Mallory would want to get captured if it gives him an opportunity to get access to SCP 458, pizza wasn't invented yet in his world and after Cro introduced him to it he's clearly developed a little bit of an addiction (yes he also likes pineapple because Cronan had introduced him to pizza via his own favorite so...)
Basically Dr Grim uses a lot of his salary to feed a deity pizza and other junk food but in exchange said deity has to do most of the grocery shopping in general any other time... thank goodness they're very active people because most people that see Grim the twig wouldn't BELIEVE how much junk food he consumes every week.
Both roommates likely despise whenever Cro has to be away from home (example: to work on-site for a while, etc.) because Mal isn't willing to deal with people and technically neither is Cro when among co-workers. So junk food in those times aren't common and they're forced to be full on healthy at those times... oh well.
Their dog is probably also hecking spoiled, as she deserves to be :)
