Why can things never be simple, or am I just getting old?

So yesterday was the youngsters birthday. As per family tradition we went off to a favourite steak house for a meal and some present opening.
One of the presents was a Star wars DARTH VADER light sabre......the deluxe flashing noisy model.
Once the paper shredding box ripping part was over, it was time to get this to work.
Lets try the big red button....hey the colour changes, but the sabre remaned ominously silent.
Disappointment clouded the little face, instructions got read and a return to the retailer loomed on the horizon.
Excuse me sir, I heard. I looked up and there was the manager of the steak house. "Having a problem with your light sabre" he asked. "Yup, thing doesn't work." "I had the same problem, took it back and ranted and raved" he said. "The shop assistant took it and pressed it there" he said while pushing on a concealed switch and voila it worked.....
Maybe this new technology is beyond me.......
