Aww sympathy is coming from me as I had a similar experience yesterday - reckon it's the cold weather. I was wandering round TK Maxx with my sister and we'd done a good tour of the shop, chatting away, laughing up the stairs, down the stairs when I felt strangely drawn to the boxes of sweets at the front of the shop. Said to my sister "I'd better check my sugar in a bit" the words were'nt out of my mouth when I thought Argh! I need help! I checked and it was 2.9. My sister who is a very bossy cow took over! We were stood by some furniture for sale and she said "sit down now" I refused in a typical hypo stroppy way. She ordered me to sit down so I did clutching my jelly babies and shoving them in my mouth as fast as I could. The security guy had his eye on us ( I suppose all potential shop lifters sit and eat jelly babies for a while first) and eventually a young shop assistant came over and said "are you ok?" I said "no" so he said "can you stand up, you can't sit there" Lol - my sister gave him a talk about diabetes and he went and fetched a chair.
The laugh was he then said "you can't sit on the furniture that's for sale cos someone did once before and it broke!" he added "it was ?300 too" Lol - don't buy furniture from there then folks!!
