Shocking observation!

<p>I was having lunch on 26 Jun and sat facing towards the kitchen exit/entrance when I observed a female waitress with a tray containg a glass of water about to exit when another female waitress walked past her and picked up the glass and took a sip of water from the glass and replaced it to the tray. The waitress with the tray then casually continued into the dining area and delivered the same glass of water to a customer!! Shocking</p>
