Normal
Even with the auto charge there is nothing preventing you from putting a little extra in an envelope and giving it to the person(s) you believe is/are deserving. That is how I did it on the last two cruises. Otherwise you have to carry on board over $140 just for tips. I think I gave out an extra $50 on each of the last two cruises and made sure the people I gave the extra tip to understood it was in addition to the normal tip (not instead of the normal tip).
