Office Tip: Respond verbally when knocking occurs at the office
restroom door  In the course of the workday I realized something
that not everyone may be aware of when it comes to office
restrooms in the typical corporate American setup. In an effort
to be of assistance to my international friends who may have yet
to experience this phenomena, I hereby post the following public
service advisory.  If you find yourself in a corporate restroom,
and someone knocks at the door of said restroom, respond with a
simple verbal emission that alerts the knocking individual to
your presence. The reason for this is that the person knocking
is most likely a member of the janitorial/custodial staff, and
they have arrived to service the restroom. The majority of the
time, they are of the opposite gender. This knocking serves to
offer you the opportunity to prevent them entering the restroom
while you are still conducting your restroom transaction(s),
thereby saving yourself some degree of embarrassment and/or
awkwardness.  A
