What if u 30 mins away from completing will u get in trouble

I beleive the best approach is to contact whatever agency you report your community service work hours to (probably Community Justice Services or your probation officer), ask for additional time to complete the community service BEFORE the time runs out, and have a plan on when the remaining 30 minutes will be done. This MIGHT avoid you being referred back to the Judge.  However, even if you are referred back to the judge - do the remaining 30 minutes BEFORE the court date and have proof of that - the judge will likely accept it.
