Agree with all of the above; perhaps the comment re size of helping is interestingly.
By trying to be hospitable, I think that some places can spoil a meal, for me at least. I have a good appetite, but being faced with mountains of food really puts me off! I know that others on this forum disagree.
That said, much better than the opposite, I suppose, and I haven't ever found that tavernas try and skimp on main courses by laying out large but filling first courses. Plakias remains a remarkable, genuinely hospitable, place, to my mind.
