Is it normal now to go to a christening and pay for your own food?

[ssd]

We've been invited to a friends dds christening. When our got christened many moons ago we paid for everyone to have lunch afterwards.
But the invite says please come to christening at 12 then lunch at a lovely pub at 1. The pub is called xxx and the food is very reasonable.

I'm quite taken aback, is this how it works now?
We all go to the place of their choosing and pay our own meals?

The only christenings I have been to have been to the Church and then back to either their house or grandparents house for sandwiches, tea and cake (and a glass of prosecco if you're lucky).
