(Note: I’m a customer and overhear this exchange while waiting in line.)

Barista: “Here’s your change… have a nice day.”

Customer: “You know, you haven’t smiled once.”

Barista: “Sorry.”

Customer: “I’m so sick of the attitude of people in the service industry! Is it so hard to give your customers a smile as you’re pouring water through beans? You all are so arrogant, it makes me sick!”

Barista: *eyes begin to well up*

Customer: “Why aren’t you smiling?!”

Barista: “…because my father died last night.”

(At this point, you could hear a pin drop. The customer is literally glared out of the shop, forgetting her coffee.)
