Part of my job is enforcing the rules, but half the time I'm not sure I know them well enough myself. Someone challenges a call I made, quotes some line back at me, and I fold because I can't say for certain they're wrong. I hate that hesitation, standing there enforcing something I only half understand.
More people experience this than they realize.
You're supposed to enforce the rules but don't know them well enough to do it with confidence.
