Late lunch

One thing that annoys me, is to be invited for lunch and find that no one has started the meal when you get there.
So, you turn up at one for one thirty and eventually eat around three thirty in the afternoon.
It may sound niggardly, when after all, you do get a meal.
When I used to cook for all and sundry, I would be up early doing as much pre preparation as possible in advance.
If I say we'll eat at one thirty, we eat at one thirty.
