Just had a text exchange...this one has been there for 12yrs and is also a manager

Her: Is there another keg of x in the cooler, the keg we tapped looks and tastes like xx for some reason.
Me: Oh you mean to tell me the keg that was clearly marked xx that got tapped tastes like xx? What a novel concept. There may be another keg of x at the very back bottom, gonna have to work for it a bit.
Her: Oh sorry. I just got here and wasn't sure, didn't mean to disturb you.
Me: No worries I just find it ironic that I clearly labeled the xx kegs so this wouldn't happen..and here we are.
