I'm on the side of the fence that you should not bring mugs from 2002 (or whatever year you have) and use them at the fountain station. Just my humble opinion and you can do whatever you want.
But.......if you go multiple times in the same year and the mugs are still the same, can they be re-used in the same year? I think this would be the exception that would be acceptable.
Thoughts???
