Should the person greeting and seating customers get a tip? Should the people running food from kitchen to table? Cooks? If any of the above are a yes, then unless you want to tip each one in cash individually, you need them to split tips at the end of the night amongst themselves.
The fact that tips technically need to be reported to the IRS and thus your employer aside, I believe it is a legally fireable offense to pocket cash in order to avoid any policies on splitting it with others working the same shift.
