You know what pisses me off...MISSING THE BUS OR TRAIN!! Every day before I go to the bus station I will use 131500.com to check the bus timetable. Even if I go to the bus stop 10 minutes earlier, the bus still doesn't come! That makes it really hard for me to manage my time and leads to me coming late for dates and meetings. The worst part is that I have to wait for the next bus for 45 minutes.
