When they were alive my parents would host a pioneer appreciation dinner for the pioneers and their husband/wife. They would host an elder/ms appreciation dinner for them and their wives. They would host a group appreciation dinner for their kingdom hall group for the entire families. They would host most if not all the members of the congregation on an individual basis at least once each during the calendar year. My parents were two of the most generous hospitable people you could have ever had the pleasure to know. They epitomized what a Christian should have been, not just to other JW's but to complete strangers.
Of course when they got old enough to no longer be financially useful to, or physically capable of being used and abused by the lazy JDubs they were promptly kicked to the curb. I have made reference to comments each of them made about JW's just shortly before their deaths.
