Waited for BEST bus 306 LTD at Nafa Bus Stop for an exact 25 minutes. The bus that google maps showed was scheduled to arrive at 7.59 pm came at 8:17 pm! This was my third attempt to take this bus as it took LBS and would drop me right outside my home. First two times I could not wait for more than 20-25 minutes! So I would say it is generally late, though the live location of bus said that it arrived at 8.06 pm (and I could see it online but bus was not there, it actually arrived at 8.17 pm).
