My experience with Witnesses far and wide is that they ARE some of the cheapest, stingiest people.
Tell me about it.
Ever been to a restaurant with more than 5 other J-dubs? We now avoid going to large group dinners with JWs. Every single time the bill comes up wayyyy short. Funnily enough, whenever we go to dinner with our non-JW friends, the exact opposite happens and either there's too much money "in the pot" or someone decides to just buy dinner for the table.
