<p>10:8 <i>And into whatever city you enter, if they welcome you, eat such things as are set before you</i>- See on 1 Cor. 9:22; 10:27. I don't think the Lord simply means 'Don't be fussy about your food, be grateful for what's on your plate'. To eat together had religious dimensions. You ate together as a sign of fellowship. So I take the Lord to be meaning that they should accept whatever fellowship was offered to them, and work from within that setting to convince men of the truth of Christ.</p>
