Friend's Birthday Treat

[DoubleTime]

I offered to take a friend for a birthday lunch, my treat, asking when she was free and where she would like to go. She picked a bar and a time and we agreed this last week, she said she would book the table for 1pm tomorrow. After 7pm this evening she contacts me unexpectedly to say she could only get a table at 11am. A bit surprised I asked her about lunch and offered an alternative (checked it had a free table 1pm tomorrow and it was somewhere we had talked of going before so I knew she would like). She said no, she doesn't usually eat lunch, that she was happy with the 11am. I don't have time to sort out a replacement prezzie, I had just got her a small thing as lunch was to be my treat. Asked did she prefer a dinner instead of a lunch and she said she had plans tomorrow for dinner.
I feel a bit irritated that she didn't ever say she didn't eat lunch, she didn't book the table until late today presumably and found they couldn't do 1pm, but am I being unreasonable ?

just try to write a poem for them.

Thank you to those who sensibly pointed out that it looks like she has prioritised her evening plans, I think you are probably right although that was an interesting suggestion @Etherealcelestialbeing and it would be a really nice ending and definitely worth the round trip for a coffee to hear that news.

Since it wasn't clear from my initial post and it seemed to be an issue - she picked the date/time/venue. I asked a while back would she like to do something for her birthday, such as lunch. She could have suggested something else, we could have eaten later, or met in January.

Since the intention was a birthday gesture I can't cancel because she has changed it, but I wouldn't have agreed to do the travelling just for a quick coffee had I known before. And you're right @Finlesswonder it feels like my well-meant birthday intentions have fallen kind of flat, and tomorrow will be rushed trying to get something else in place and to get there on time.

How did it go?

I had a nice time with her thanks @Whattheheckcarer and managed to top up her prezzie beforehand but ended up getting a taxi there to make it on time. And she did have a meal (prompted by her) although it seemed early at 11am for what she ordered (fries on the side). It wasn't a boozy brunch and we had to leave by 12.30pm as they were setting up a table for a big group, but it was nice to see her.
