Airport staff

I feel sorry for airport staff. So often they must be asked the most basic of questions fifty times a day.

"Where is gate 12?"
"Follow that gigantic sign over there that indicates all gates between 1 and 20."
"Is this the way to gate 12?"
"Yes. Keep following those big signs."
"Is this gate 12?"
"Yes. Do I need it stamped on my forehead?"

On my return flight from Boston, I checked on to my international flight myself. Both my passport and my luggage was confirmed/tagged by a floating staff member. This approach was much faster and staff efficient compared to the current Australian setup for domestic flights. Perhaps it is just a matter of time.
