I had one in a meeting I had my workbag with me so knowing I had gone hypo with shakes and sweats I just got my meter tested confirmed it was a hypo and took some glucogel out of my bag and guzzled it sat still with meter on table ready to re test 10-15 mins later
I was asked if I was alright to which I replied no not really but I will be soon
Re tested and had gone up sufficiently
In the meantime they suspended the meeting for a comfort break for everyone
I was ok to carry on after the comfort break
Also had that hypo feeling when driving and soon pulled over to treat it. Like you I have myself plenty of time sitting and checking bloods before driving off
I have 2 bottles lucozade at all times in the car boot and dextrose in glove box
Hypos are awful full stop
