i was on SBS 2801T (AMDEP 162), when
something happened. nobody pressed the bell, but when the BC tried
the exit, after closing, bus stopping sign popped, then try open,
disappeared, close, again it popped out. this causes confusion,
when some people want to alight, they thought got bus stopping
sign, so they thought it will stop, but it skipped, because nobody
pressed the bell. it was resolved after few stops later.
