Usually after the second day I know the bartenders or severs I like and appreciate.  I carry a wad of singles with me and i discreetly slip a buck into the folder they give you to sign.  I really get great service regardless of the line.  One waitress from the Ukrainians said to me "all the crew like Mr. Todd".. Word spreads fast amongst the crew as to whom is nice and tips

  Thats is something I enjoy doing.  I never expect anyone to do that but I ceel good doing it.
