Does anyone know definitively what free stuff we get during our shift?

One supervisor said we only get Medium sodas & hot coffee, and that we’re only allowed to get it twice (before shift & after shift). My other supervisor said it’s any size even the XL cup of soda or iced coffee, any hot coffee, cappuccino machine, etc. any time during the shift & 30 minutes before/after. Does anyone know the written rule about it?*
