I"m confused; why does your TA care about the gratuities? You usually have the choice to pay them the traditional way (envelopes at the end of the cruise) or adding them to your account. Tell him/her YOU'LL decide how they will be paid. I' ve never had a TA even mention tips, let alone tell me how to pay them. Unless Celebrity is doing something different recently ( 8 seven cruises with them so far), handle it the way you so fit.
