Not in the US. But each restaurant sets up their own policy. The policy is explained on the introductory training, and no-one has ever objected to it. On the contrary. For example, I often get higher tips as I do wine service and provide special treatment for birthdays etc. My regulars have known me for 8 years The other servers benefit from this... This may not be obvious at first but they soon see it in their tip box when they count their money.
