I am of two minds on this issue. With automated tipping a have can tip as much as I want, even more than I brought, as it is charged to my credit card. I will always wonder whether the server/steward received any or the entire tip I intended for them to have. With the traditional (envelope) method I am fairly certain the employee receives what I intended them to have, however I have to risk having that much more cash around and make sure I budget my cash spending to insure having enough left to tip the appropriate amount. So far I have only used the sink or swim card method of tipping, but am considering changing to traditional, or some combination of both.
