That reminds me of a science trip I went on last year with my entire year group... we stopped at a service station, and one of the guys in my class found a huge moth on the ceiling, so he scooped it into a bag of sweets he was about to buy, then paid for the sweets and tried to return them, saying he found a moth in there. Haha needless to say, he didn't get a refund.

And he kept the moth. In fact he let it go out of the fire escape of the coach and it hit the windscreen of the car behind us. The person driving must have been so scared because this thing was like a small bird!
