Best not to say no anyway. At jobs like that, best to go a little above the bar so you can negotiate later on down the road. 

Can't say I have anything to complain about at work today. I, uh, had to buy a candy bar to stay awake because I went to a drive-in movie the night before? That's not a real problem though.

I can complain about dental insurance now I guess. They took my money but they still playin' like my application is pending. What's that? I paid you, I'm a customer now, pay for my cavities. (and no, this isn't a waiting period. This plan doesn't have waiting periods in my state. It's just ...pending.)
