想在craiglist买monterey bay aquarium ticket, 从craiglist:
"Two monterey bay aquarium passes.
$15 per one day pass. $20 per ticket deposit will be fully refunded when the
passes are returned the same evening or the next morning."
问题: 他怎么能"fully refunded when the passes are returned the same evening
or the next morning". ticket不是在aquarium 收回去了吗? 还能接着用?
