I absolutely do not like missing calls.
Because then you have to call back,
and then the gum-chewing receoptionist will go "who?",
and then you repeat your name 3 times,
and then she goes "yes?"
and then you have to remind her that you're calling back because someone gave you a missed call,
and then she goes "oh.... ok, hold on",
and then she screams "who called for...*and this is where fur elise starts to play*,
and then someone else answers and says "hello?",
and then you have to repeat the purpose of your call yet again,
and then you repeat your name another 2 times,
and then they go "OH,"
check your surname,
and then say "oh yes, I'm (insert name here), calling from Singtel, I'd like to do a short survey."
