Gary is not completely accurate in that statement. From the Carnival website-
"For your convenience, we automatically charge the gratuities for dining and stateroom staff to your onboard Sail & Sign account. The total amount is $10.00 per guest, per day (our recommended guideline) as follows:
$ 3.50 Per Day Stateroom Services
$ 5.50 Per Day Dining Room Services
$ 1.00 Per Day Alternative Services: distributed to other kitchen and hotel service staff "
So only $1 per day goes into the so called "pool" for the rest of the crew. Most of those are not counting on tips for their income. Your stewards and your waiters get MOST of their income from tips, so they get the lion's share.
As for giving extra tips, we do that when the service warrants it. (We always leave the automatic tips in place and reward extra when it is deserved.) Note that the bar service has a 15% tip added to the amount so you do not have to tip the bar waiters extra unless they have done something super special for you.
Hope that clears it up.
