(An older, unkempt-looking man comes up to my counter.)

Me: “Hello, and welcome to [restaurant]. Can I take your order, sir?”

Customer: “Uh, yeah. Sure.”

Me: “What would you like?”

Customer: *pauses* “What do you want?”

Me: “Sir, what would you like to eat?”

Customer: “Stop rushing me, woman! Let me have some coffee!”

Me: “I’m sorry, sir. What kind of coffee would you like? We have—”

(The customer throws a twenty dollar bill on the counter and starts shouting profanities at me and the other customers in the line.)

Customer: “D*** kids these days! Just give me my f***ing coffee, b****!”

Me: “I apologize, sir, but I can’t serve you if you don’t tell me what kind of coffee you would like. Unfortunately, you are disrupting the other patrons and I’m going to have to ask you to leave.”

Customer: “I’LL LEAVE ‘CUZ I WANT TO LEAVE!” *leaves in a huff*

(In his haste, the customer left his twenty dollar bill on the counter. He never returned, so I ended up paying for the next few customers’ meals with the money that he left behind.)
