6.48am in the morning. Bus door did not open. Door stated turn clockwise to unlock so I did. A tiny red sign said in an emergency which the raging driver pointed out to me after shouting no one will get to the airport after what you done. Continued to raise his voice in front of all the passengers. I told him the sign confused me. 2nd time in years using the coach. Please change your signs or have the door open sooner because I thought I was causing the delay hence turning door clockwise. Visibility was bad as its pitch dark. It was the morning of storm ISHA too. I was blown to bits outside and could not see nor understand what the driver was signalling to me through the door. ..Sign should state please wait for driver to open door. Do NOT turn handle clockwise unless in an emergency.
