Why does nobody do first aid?

I had a serious life threatening event at Ikea today. Hypoglycemia. My bloodglucose was at 43. I tried asking people other shoppers for help to get me first aid and they ALL IGNORED ME. One lady looked at me and blankly said, "I don't have time. Not my problem." When all she would have to do was call for an Ikea personal. They were like literally 2 meters away.

I eventually dropped to all 4s and screamed for help and a cashier came rushing. but seriously WTF Berlin. In what time are we living that "you do not have time to do first aid." Do you really care so little about other people?

How can you just walk away and not bother.

Edit: I spoke German. I said: "Entschuldigung bitte holen sie jemand ich brauche medizinische Hilfe." And showed her my phone with the red low glucose warning

Edit 2: most of you did an awesome example on blaming me for having a medical problem. I hope you all will never need help, because you are no better than the lady walking away. Won't answer any more questions.
