Light-hearted
If I'm going over to someone's house (invited), most people I know will offer a hot drink pretty much as soon as I've walked through the door. And I will do the same if anyone comes over.
This is the proper way isn't it?!
Whenever we go to PIL we have to wait aaaaages before we're offered anything and recently we only had time to pop by for just over an hour and we didn't have owt moist!
YANBU - a brew as soon as you're over the threshold
YABU - patience is a virtue
