Once when I was 21 I was on the tube going home after work when I suddenly felt really really awful and had to get off the train. I wandered up to the ticket barrier when a guard saw me and asked me if I was OK. I was feeling so faint I couldn't even talk I just said I felt sick. He then took me into the back room where he and his colleagues made me sweet tea, toast and talked to me for ages until I felt better then called me a cab home, they were really concerned.
I know it sounds really silly but I have never forgotten how sweet they were to me and how much better I felt for it and it was so long ago and such a little thing - does anyone have any similar experiences?
