In 1963 when I was 20 I worked for a company in Brussels which made magnetic colorful letters. Each year they exposed in Nürnberg at a worldwide famous toy fair in Germany.
My job was to translate into French and to look cute and friendly and keep the stand where our products were shown. I was alone and hungry, it was around noon, my boss and another coworker had gone for lunch, but the hall was still packed with people. I took my sandwich out of my bag and put it on the floor so that nobody could see it and from time to time I looked around, bent down and took a bite.
A few stands further I heard people laughing and laughing and told myself that they must show something very funny and that's why probably I had nobody at our stand.
Then I noticed that one of my nylon stockings was loose (there were no panties yet) and had to be fixed to the garters. As only my top could be seen, I pulled up my skirt and fixed the clip. Another bout of loud laughter. I became curious and as my stocking was fixed I walked over there to have a look and to find out why people were laughing so much and evidently were very amused.
When I approached the laughter even increased and I didn't understand a thing. And then I saw what happened ! The exposed object was a video camera (very rare at that time) directed right to my stand and you could even see what happened behind the counter ! Now I understood why there was so much laughter, everybody had seen me eating under the counter and also my legs while I fixed my stocking !
What should I do ? getting a red face and look ashamed or laughing ? I preferred to laugh with them !
