Express Bull****

I usually take the Areyeng bus to get to work at around 7:40 latest at 7:45 in the morning. However though, yesterday 29/01/19 i waited for the bus as per usual and when it finally arrived, the driver asked me for my destination.I then told him i was to jump off at General Pitso station. He then asked me to take the next bus because he was an express bus. Today the same thing happened with two drivers and had to take the 8:00 am , which made me extremely late as i start work at 8:00. Now i want to know whats going on?
