40 minutes delay for boarding. Seats were old and not comfortable, had difficult time in setting pushback options. The bus driver had a heated arguments with other vehicle driver. Next, the bus hit a another transport vehicle with front windows got smashed and had some other problems also leading them to transfer all passengers to other vehicle. Luckily we didn't have any injuries or so. Do, the whole travel was below average and our safety was in jeopardy. May be this is an one of scenario, but this was our experience.
