How is it possible that my flight was delayed for not having a crew?

30. I asked her if we actually had a crew assigned...

As opposed to one that MIGHT make it. I said I was asking because I needed to know if the flight had the potential of being cancelled since I work in the morning. She stopped helping me and proceeded to tell me she didn't appreciate my tone. Sure I was not happy but I don't think this woman understood what it means to have a bad tone. I've seen people rip airline employees apart before. I was doing nothing of the sort. I just wanted to know if a crew was actually on its way and why they weren't there in the first place. I think that's a reasonable request. If she didn't have the answers she should have said so instead of beating around the bush trying to find flights for me in the morning when she knew I had to get in tonight for work.

I asked another employee and she literally made a story up that it was flying from JFK. It was actually from San Diego and had been at SFO on time for two hours prior.
None of these people understood that I just wanted to know what was going on. I didn't want to be lied to or pushed around. That's not good customer service.
