I invited someone to Sunday lunch. I asked before hand if what I was planning to cook would appeal to them a week in advance so they could have told me if they wanted something else - I am easy about a Sunday roast - no odds to me if they prefer pork or beef or lamb or whatever.
Then when checking beforehand to see if they were still on track for arriving at the time arranged (to get my cooking timings right so it would be ready for when they arrived which was the meal time) it turned out they were stopped to have a snack en route.
I'm not stingy with food and I like to think my hygiene standards are good and they were not travelling far - much less than an hour door to door - so it threw me a bit.
We had a nice time and they ate what I served up but it just made me feel a bit confused.
