My awful experience happened when I was in Primary 1, at my grandfather's birthday banquet, and my aunt and uncles of my mum's family were all there. On that day we went to the "New Territories Big Restaurant", but this restaurant is closed now.
My mum was the first one who arrived at the restaurant to wait for the others to come. Then, I saw something bad. A waiter sneezed into the serviette when he was folding them into a cone shape, but I didn't know that's awful at that time. When everyone had arrived and started eating, my grandmother's chair suddenly shattered in the middle of the banquet.
I think that restaurant is really bad, because the hygiere of the waiter was very poor.
Thank Goodness that restaurant was closed.
