I do that, too, the breaking down into ones, fives and tens. I carry only one days worth of tip money on me and then pack the rest in several different ways in my luggage (won't reveal that since I sometimes travel with other AUers. h34r: :help: ). The tip money I carry with me is put into an envelope just for that so that I don't accidentally spend it on something else.I have a trip from Virginia to Arizona coming up later this year: four days, three nights each way. I'm very much looking forward to the trip, but calculating the cost of the tips is kind of horrifying, assuming I do make all the meals and also tip the sleeper attendant each day. Particularly since I don't carry much cash these days.
I came up with a need for 33 ones, 7 fives, and 8 tens, or $148 total. Seems like there has to be a better way. I'd rather pay it up front in the fare.
