And which guy could safely leave it at home?
If you guessed that the ER doctor on call needs his cell phone with him at all times, you win! Having his phone could save lives. And your prize for picking the ER doctor is your choice of a) a library card; b) a trip to a museum; or c) a romantic evening with your significant other.
If you picked this guy, you lose. And you’re probably one of the 6 billion or so non-ER doctors who pretty much never need their phone. Everything that’s happening on it can wait until you get home. Your punishment for picking loser guy is a) a library card; b) a trip to a museum; or c) a romantic evening with your significant other.
