This past summer I worked at Drench & Drown water park's snackbar.
As you may have noticed, Coke had their promotion "Share a Coke with..." back in full swing again. This summer, instead of names like "Lucy" or "Ricky" the cans suggested you share a Coke with "your sweetheart" or "your better half" or "a favorite."
One afternoon Dick McJackass, the local high school delinquent, walked into the snack bar like he was walking onto a yacht, and bought a Coke. I grabbed the first one off the shelf, handed it to him, and moved on to the next person.
A few minutes later he was back. He shoved the person who I was serving out of the way, slammed the open can down on the counter, and began yelling.
Dick McJackass: "What is this?"
Craig: "Uh, it's the Coke you just bought."
Dick McJackass: "I KNOW THAT! Are you calling me a girl?"
Craig: "No, I'm helping this lady. You just bought a Coke."
Dick McJackass: "The can says 'Share a Coke with a Sis!' Do I look like a sis to you?"
Craig: "No. I just handed you the next can in the pack. It doesn't mean anything."
Dick McJackass: "Bullshit. I don't even have a sister. I want my money back, and a new Coke."
Craig: "I'm not allowed to do that. You already opened it."
Dick McJackass: "I want to talk to your boss."
Mr. Incharge: "I'm right over here, Dick. You can't have a new Coke or a refund. Get lost."
Dick McJackass: "Your counter help insults me and you support him treating a customer like that? You need to do something about that."
Mr. Incharge: "Okay. Let me see your pass for the day."
Dick McJackass: "Here."
Mr. Incharge: "Thanks. Get out of the park, your pass expired." (tears pass to shreds).
Dick McJackass: "You can't do that!"
Mr. Incharge: "I just did. You better call your mom for a ride home. If you don't, I will."
Dick didn't come back the rest of the Summer. It was awesome.
