While I worked at Disney World, this guy got really mad at me because I couldn't give him a receipt for his popcorn. Not wouldn't, couldn't.
See, at the outdoor popcorn and ice cream stands, we don't give out receipts for cash transactions. That's just how it is--we can't change that even if we wanted to. It makes things faster and saves a lot of paper, considering 99% of people who use cash don't care about the receipt anyway--especially if it's just for popcorn and a coke.
After I took the guy's order and gave him his change, I voided an item that I had accidentally rung up a few transitions ago, and needed to take care of before I forgot. Now void transactions do produce receipts, and we're required to keep them. So I finished his order, gave him his change, then did the void--in that order. After that I gave him his popcorn he asked for a receipt, and I told him we don't give them out for cash transactions.
Then he just looks at me, as though I'd just told him the popcorn was flavored with mud. He asked me to repeat myself, and I did. We don't get receipts for cash. He asks me why, and I said because it expedites things and is generally much more convenient on both ends. So he sets his popcorn down, reaches into his pocket, and pulls out a receipt. He points to it and says, "These people gave me a receipt."
So I took a look at it. It was from the Main Street Bakery, an indoor food and beverage location that wasn't related to my department in the least. And I explain that to him, and clarify that it's only the outdoor stands that don't do receipts for cash. He gives me that look again, and mentions the receipt I put away after I took his order.
I realized how confusing that must have been on his end, so I explained to him what it was. Now he's looking at me all skeptically, as though I'm trying to trick him and he's not buying it. I tell him "I'll show you the receipt if you want," and I start reaching for the receipt bag. But he just waves his hand and says, "Just forget it" and walks away.
After that I couldn't help but stare for a moment. I thought, did that seriously just happen? Did that guy really just walk away thinking I was trying to jip him out of his receipt? But he did. The woman who was behind him this whole time stepped up, kind of chuckled and said "People can be crazy, huh?" And I said yeah. They can be.
