I hate it when I go into stores and the staff shout at each other across the store like it's a fish market. I hate it even more when the shouting is about inane stuff like "You giler dia ke? I don't think he's that into you lah!"
It's such an off-putting experience that I usually stop my browsing and walk right out of the store. Why doesn't management teach their staff that this is not a fish market and customers don't care to hear about your Saturday night plans being yelled across back and forth?
