Sort of continued from yesterday.

Guardian:
你要是想知道我每天有没有按时吃饭，你加入我们特调处不就知道了吗 (if you want to know whether I'm eating regular meals daily, you can join our SID. I'm not sure what's happening at the end of this sentence grammatically...)
你到底有没有在听我说话？(have you been listening to me or not?)
你好，你有没有看见一个脸上留着胡子然后嘴里可能含着棒棒糖的这样的一个男人？(Shen Wei's on-point description of Zhao Yunlan, a man with a beard and mustache who might have a lollipop in his mouth)

My practice:
你昨天有没有喝完了咖啡？
等火车来的时候，我们有没有买小吃的时间？
