30 sec is 30 sec. It's the same for everyone. Once you get to your lie, no one should have to tell any player a clock's been started.
In reality, the 30 sec clock is a lot like speeding. Go a bit over once in a while, probs never get called on it. But the more frequently you do it (or the more eggregious a single incident is), the more you invite the call.
If someone speeds all the time, it seems ridiculous they should get bent out of shape when they finally get a ticket. Nikko's a habitual speeder, and he finally got ticketed.
Instead of just paying the fine and moving on, he pitched a fit and ended up in jail for a more serious violation.
