I don't know that I would have reacted that way, especially on a date with a man I didn't know very well yet. I would have been angry too, initially, but once I heard the circumstances I would have asked was there anything I could do to help support him.

I want my good friends to drop everything and come running if necessary, just like I want my relatives to do the same. That this man does that, would make him special in my getting-to-know-you book, I'd really look forward to getting to be special to him in that way. That he had enough presence of mind in an emergency to pay the bill so I didn't have to, that would be icing on the cake. I'm grown up and can find my way home, don't go out without resources to take care of myself, especially in case something happens to the person I'm with (and, always, identify/medical ID, etc. in case something happens to me too).

However, it is good that it happened when it did too so you aren't disappointed; hopefully he wasn't either.
