It's often been said that the customer is always right. I would like to point out that customers who think like this are not always right. In this case, the customer is either:
A. Wrong
B. An Idiot
C. An Asshole
D. All of the above
Fortunately, no customers have used this phrase in my presence. If they do, I'll scream. At them.
Another thing I've noticed recently: Cards. Why do people put the cards in the envelopes before they get their stuff rung up? Don't these morons realize that I have to take them out to scan them? Please, arrange your cards so the cards are not in the envelopes and the bar codes are facing out.
