Interesting, I didn't know that!
I was thinking the same thing when I read it, But the doubt seems somewhat reasonable. Its not exactly a common thing for a fall from standing, you usualy see the spontaneous erection in people with spinal trauma like a car crash or someone who jumped off a 8 storry building. Its still not right for the operator to ask if its a joke though I find they usually take people seriously IRL. Although telling the operator doesn't help much it would already be rtc because of the lowered Loc. I wonder if the operator would pass on that info to the medics.
I understand the KFG worker thinking that the fall in front of him is what caused the injury but the 911 operator should have known better. He could have been hit by a car or was in a car accident or fell from a great height and then wandered off confused because brain injury. Two, three, five blocks away and THEN he collapses. It felt like the Mangaka knew that that's a sign of brain trauma but then decided to make the 911 operator stupid for some reason. It's just a nit pick I know but it really bothered me. Maybe I just like to believe that 911 operators, EMT's, doctors etc are competent people even in fiction.
It's a nit pick but the 911 operator asking if the call was a prank because he mentioned the erection. A spontaneous erection (in that situation) is a sign of a serious brain injury. Any 911 operator worth their salt would know this. After he mentioned that the person was passed out and bleeding from the head, the operator wouldn't assume it was a prank because he said the person had an erection. That really irritated me, i dont know why. Griping aside I really like this, I'm looking forward to the developing of the characters and story.
P.S The coupon that had the KF(C)G Finger Wrap looks like the KFC Twister that they used to sell here in the states. It was delicious and they discontinued it SONOFABI#*%^×_$;=<÷,'=<$;#,÷:&$<$>. Bring it back KFC!!!!! Also the girl in the beginning (the one that we're supposed to hate) I feel sorry for her. Her parents are CLEARLY not doing a good job raising her. She's forced to have sex with random men, watches her mother get high and doesn't seem to have anyone in her life that's a positive role model. No wonder she acts the way she acts.
