Player Specific jobs

[FBspitty]

Hello i have just finished reading a topic that helped me with usergroup specific jobs but now i want player specific i was wondering if and how this would work

  customCheck = function(ply) return ply:GetNWString("usergroup") == "owner" end,

but as something like

  customCheck = function(ply) return ply:GetNWString("STEAMID") == "STEAMIDHERE" end,

customCheck = function( ply ) return ply:SteamID() == "STEAM_(numbers)" end

This is just my method, hope it helps.
