We had 12 guests in our training restaurant and there were only 12 of us students to cope with the rush. This meant panic stations for us "freshers".
It was my course mate's task to swap the clear glasses on the table for ones with green stems to match the green wine bottle. He was holding the tray of four green-stemmed glasses in his left hand, but as he reached for a glass, his left hand leaned with him and the four glasses toppled over. Worse still, one glass slipped off the tray, fell onto an unfortunate lady's head and smashed into tiny pieces.
All the diners were elderly and this particular lady seemed unaware that there were shards of glass in her carefully set hairdo. Or maybe she was trying to pretend nothing had happened - customers eating in training restaurants are supposed to be there at their own risk, aren't they?
Naturally, he went bright red and started kicking all the debris under the table.
He stood behind her, his eyes transfixed on the old lady's head as he picked out the bits of glass from her hair!
The rest of us had collapsed into fits of giggles. It was all the more amusing because the customers didn't seem to be fully aware of what was going on.
Eventually, after much whispering and muffled sniggers, our tutor came to the rescue and sorted everything out. Luckily, no-one was hurt!
