Where's the glass?

The waitress was about to refill the "Sprite" (soft drink) for the table when she discovered something amissed........

Waitress: "Excuse me, I realised that one glass is missing from the table .... "

When everyone was trying to find the cause of the lost glass, then one of the kids slowly brought up the glass to the table.

Kid: "I was just trying to try my luck to see if I could get the F&N Orange if this Sprite is gone."

Waitress: "You could simply request for another glass and I will be glad to serve you."

Lesson learnt: Ask and you'll be given ;D
