Poll: How much do you tip for wine service?

A friend and I were talking about this - I thought I'd put it up here for discussion and a poll.

You and a friend are out at a restaurant. Let's say it's just a regular restuarant - not a wine bar. You order $100 worth of food and a $100 bottle of wine. The service is good. Solid. How much do you tip? Specifically - do you tip differently for wine service than food service in a restuarant?

Does it depend on the quality of the wine service? If they pour your $100 prize into cheap little water glasses on the table vs. presenting large clean high quality stemware does it make a difference?

How about if it's BYOB? You bring the wine and to justify the (say) $25 corkage fee you bring a really nice one. $100 retail. It would be $250+ if it were on the wine list at the restaurant. Do you pay more for someone to pour your own expensive wine than if it was a $10 bottle?

Tell us what you think. Answer the poll below and if you'd like to describe why leave a comment below.

Thanks for your thoughts!
