Well, I guess it depends on a couple of factors.

1. Are you a tipper in general ? Could be that you simply think toking - or rather gifting - the host is the right thing to do (I've seen people tip almost every type of service giver....)

2. Do you believe a tip/gift is a good investment ? i.e. do you think your host will remember you better, pay more attention to you, get you better comps if you show him/her some love ? (not literally...)

For a more in-depth discussion (although a tad outdated) look up Max Rubin's "Comp City"...
