... if you were really frugal you could just sleep in the cafeteria...(not recommended by the way, too many bodies doing that already in a teaching hosp due to lack of call rooms) ... The most frugal resident in my yr lived at home and rented a den downtown for when he was on call/post-call/etc.
your post plus peterk's shared housing suggestion makes me wonder why some enterprising RE type doesn't buy a house near the downtown hospitals & run it as a crash pad for medical students on rotations plus residents on call?
this would permit the students & the residents to actually live somewhere else where they could have a real life. Then during intensely gruelling on call rotations they could move downtown, into the crash.
the place would probably need a live-in housekeeper. A multi-skilled. Everything from running the washer/dryer night & day to maintaining the room booking spreadsheet.
your details re exhausted clerks & residents napping in hospital cafeterias do remind me why foreign medical students who sign up for french classes at mcGill often tend to fall asleep in class though (on top of everything else, med professionals in quebec have to pass proficiency exams in both languages) ...
