Earlier this year, there was huge kerfuffle over some Pastor in the US who refused to leave a tip in a restaurant. By way of explanation, he wrote on the bill that he already gave "10% to God". Something that I never realised (coming from Europe as I do, where we don't really do tipping) is that Christiansalready have a reputation for being bad tippers - especially on a Sunday.
But is that reputation deserved? Michael Lynn, at the School of Hotel Administration, Cornell University, Ithaca, and Benjamin Katz (HCD research) ran a survey of 1,600 U.S. adults to find out.
