Someone appears to drink water as a defence mechanism when in trouble in the office. As a point is being raised or feedback given, the person always brings their glass to their mouth and will drink (or at least seem to drink) from it constantly until the conversation is over.
Is this a normal thing? Could it mean anything?
EDIT: Seeing as this question is being misunderstood and misinterpreted I will clarify the following:
I have noticed when delivering constructive feedback/criticism of a member of staffs work, as is done with other members of staff, they seem to defend their self by holding a glass to their mouth and drinking/pretending to drink
I am trying to establish if anyone else has experienced something similar in this position, and if I should be concerned the person only every performs this action when being presented with something one could deem as negative
If this person is struggling and panicking when issues/feedback is raised this needs to be handled separately to allow the person to feel more comfortable and understand I can help improve their knowledge/skill set or what ever may improve their confidence and I am trying to establish if others think this may be an approproiate course of action
