I found a formula a few years ago here on "Amtrak Unlimited" for tipping the SCA and at meals.
For couples: $5 Breakfast
$5 Lunch
$10 Dinner
$10 per night SCA
I get enough 5's and 10's for the trip plus two extra of each at the bank prior to leaving on the trip. This also eliminates having a bunch of 1's or change to carry around.
