(A customer comes to the return desk the day after Christmas.)
Customer: “This ham smells off. Smell it. I want a refund.”
Me: “I’m sorry that it was off, sir. I’ll refund you now.”
Customer: “Aren’t you going to smell it?”
Me: “Um…it’s okay. I believe you.”
Customer: “It smells terrible!”
Me: “I’m sure it does, sir, but it’s not necessary for me to smell it. I’ll just give you the refund.”
Customer: “How do you know I’m not lying if you won’t smell it?”
Me: “Sir, I am not going to smell your ham.”
Customer: “SMELL MY HAM!”

(I am a cashier in a grocery store. I have just rung up an elderly man’s groceries. Keep in mind this man is around 80 years old.)
Me: “Your total is $52.83, sir.”
Customer: *holds out hand full of change* “Can you pick out the right amount for me, honey?”
Me: “Sure.”
(I carefully start counting out change from his open hand.)
Customer: “It’s okay. I’ll let you touch my hand so I can get a thrill. Even at 80, I still get thrills, you know!”
Me: *speechless*

(Back in 1990, my mom worked at a coffee chain. She had never given incorrect change for the year she worked there. On her last day of work, a customer orders a $0.90 drink, and the total comes out to $0.99. He hands her a $1, leaves, and comes back 5 minutes later.)
Customer: “You b****, you gave me the wrong change!”
Cashier: “Well–”
Customer: *yelling* “I want to see the manager!”
Manager: *walks in* “What seems to be the problem, sir?”
Customer: “This dumba** woman gave me the wrong change! I gave her a $20 and she only gave me 1 cent back!”
Manager: *looking at cashier* “Give him $19 to make up the difference!”
Cashier: “But, he paid with a sing–”
Manager: “I said, give him back his money. God, women are so bad at math.”
(The cashier hands over the money. At the end of the day, she was fired for being exactly $19 short.)

(A customer comes to the till with a large bottle of milk.)
Customer: “Hello, I’d like to return this. It’s expired.”
Me: “It says on the receipt that you bought it last week.”
Customer: “Yes, but I haven’t used it. It’s expired.”
Me: “The expiration date is yesterday. It was well in date when you bought it.”
Customer: “Yes, but I didn’t use it, so you have to give me a refund.”
Me: “I’m afraid we can’t give a refund for that. It was within date when you bought it.”
Customer: “Well, can’t you change it, at least?”
Me: “You want to swap some expired milk for fresh milk?”
Customer: “No, just change the label so it’s in date again.”

(I am stacking the oranges, which is next to the shelf of avocados. A very well-dressed woman in her 40s comes over and starts feeling the avocados while talking to herself loudly.)
Customer: “Wouldn’t you just hate to be an avocado?”
(The woman continues feeling up the avocados.)
Customer: “Hmm. You know what? That’s actually my biggest fear. Becoming an avocado.”
