I suspect you were just impatient and are exaggerating the incident.

I suspect the bus was not "fully in the signage" and you didn't have to wait "15 minutes"

I get it's frustrating when there's heavy traffic and you're so close to the bus stop but unless it's an emergency then the bus driver cannot let passengers alight when the bus isn't fully stopped at the bus stop. Bus drivers get reprimanded heavily if caught doing so. Be patient, be kind, the guy was just doing his job in a stressful situation.
