Your example is a bit inappropriate. That fella can simply do the
teleconferencing from home. I understand there are some people who
has impt appts on weekends. I believe that fella conveniently
assume the freq for 291 for Sundays is the same as weekdays. Too
bad for him la.
Perhaps he is a housing agent, or somebody in a similar job that
works on Sundays and he missed an important meeting with a
buyer/seller.
“The bus that I boarded eventually was the bus from the
opposite bus stop 10minutes ago.
Wonder what he will comment if he missed 115. Maybe "The bus
that i boarded eventually was the bus that I just missed half an
hour ago."
