do you tip at resturants?

I have to agree with alot of seen here I tip according to how they act. I've tipped up to 50% depending on the meal and how courteous the server for me it's a balance theres being there every time I have a drink empty or even to ask about how it is tasting and then theres being there way to much. I like when the server walks by their tables just to check on your even without asking.

I had a server once I was with my fiance and she treated me like I was some stupid little teenage pervert so when I left I gave her a penny as a tip this is generally how we show our disapproval to servers where I live.
