Location: Dublin
Event: 2 hour delay.
Problem: A passenger wanted to disembark because his trip was no longer worthwhile.
Attempted solution: call after call to ground handling asking for someone to attend the aircraft and escort the individual back to the gate.
Final solution: After no response from handling, cabin crew escorted the individual the 50 yds to the gate.
Outcome: one satisfied passenger; an airport authority that reacted as if war had just been declared on the Republic.
Long-term Outcome: never meddled with airport and handling jobsworths again.
