"Hypoglycaemia"

I came in today for a flu jab. I am diabetic, and during the long wait for my injection I noticed my blood sugar levels were dropping rapidly. I asked the receptionist if I could have a glucose shot - standard hypoglycemia treatment. She clearly had no idea what I was talking about and started giggling. I asked the lady who was going to give me my flu jab, I presume she is a nurse or healthcare assistant? She also looked at me blankly and said there weren't any, but she would bring it up at the next management meeting. The lack of glucose shots was confirmed by another nurse who entered the room at that time. I said that I could not believe that a doctors' practice did not keep a stock of them. One of the nurses asked if I had any glucose in my bag, which was not helpful, and suggested that I go and buy some sweets, which was also not helpful. Two questions: 1. Do your receptionists have absolutely no medical training whatsoever, and 2. Why does the practice apparently have no quick-acting treatment for hypoglycemia - it is an incredibly common, albeit dangerous, condition, or are they keeping them locked away for a special occasion?
