I like the idea of Secret Service enrichment activities being exactly like dog enrichment. They just release a bunch of Government mooks into a room with some of those doggie treats puzzles, but I stead of beggin strips, it’s full of domestic terrorists addresses.
For easy drinks (beer, wine, or simple liquor/ soda mixes), $1 is fine. If they have to bust out a tool like a muddler or peeler, you should probably give more than $1.
