When I was in junior high school or high school, my homeroom teacher was so earnest that he encouraged us to hold a bazaar in school festival.
One day, he told us to drop to their tables and close eyes*1 when he said "If you want to hold the bazaar in school festival, raise your hand."
According to my friend, who pretended to drop to his table and peeped the result, 4 out of 40 raised their hands. In spite of the result, the homeroom teacher decided to hold the bazaar.
In fact, I was required to sell goods for 2 or 3 hours during school festival.
But, I forgot to do the job, and I went to a hot spring resort "Gakuenmae yamato no yu" with my friend(I introduced above).
My homeroom teacher must have been irritated with me.
*1:This was done to prevent students from deciding whether they raise their hands or not by observing their friends' decision.
