Getting A Bad Reading

(In my store, it’s part of our job to greet every customer and tell them about all of our current promotions, even though there’s usually signs all over the store.)

Me: “Hi there! How are you going? Just letting you know while you’re browsing that we have got a 2 for $20 sa—”

Customer: “I know! I can read, thanks!” *walks away from me*

(I shrug and walk off; people like that are better off left alone. No less than five minutes later…)

Customer: *shoves a necklace in my face* “How much is this?”

Me: “All of our prices are clearly marked on the label… so you can read right here that it is $16.99.”

Customer: *continues to ask me the prices of about five other items, all of which are clearly marked*
