It depends on the culture of halflings in that world.

In Tolkien's world, hobbits are based on early 20th century respectable rural English society. But that is entirely up to the DM (and maybe the player as well, if he is inventing a background and the DM is good at co-operative character generation.)

If I did this, the halflings would be hobbits, and the best description of hobbit manners comes from Gandalf's morning visit and (much more so) the dinner for the dwarves.

'When the silence that followed had become uncomfortable, he added: “I am just about to take tea; pray come and have some with me.” A little stiff perhaps, but he meant it kindly. And what would you do, if an uninvited dwarf came and hung his things up in your hall without a word of explanation?'

'He had a horrible thought that the cakes might run short, and then he—as the host: he knew his duty and stuck to it however painful—he might have to go without.'

Oh - and make a point of having your pocket handkerchief.
