Eat such things as are set before you

"And in the same house remain, eating and drinking such things as they give: for the labourer is worthy of his hire. Go not from house to house. And into whatsoever city ye enter, and they receive you, eat such things as are set before you:" Luke 10:7-8

This piece of advice makes sense only in an environment where there are multiple diets followed by different groups of people. Jesus and his disciples were probably keeping kosher but Jesus instructs them to eat whatever they are served. This makes sense to me: I’m vegan but when I visit someone else I eat what they serve unless they are offering a vegan alternative.
