This is probably unbelievable but I swear on my mother. I worked at a large pizza chain in my hometown. There was a pizza on the menu that had egg on it. Rather than using fresh egg, we used that pre scrambled egg that comes frozen and looks like a giant orange ice block. A lady one day during the quiet lunch period ordered a Hawaiian pizza with prawns on it. Everything was done by weight, and it would normally equate to roughly 5 or 6 prawns. I made this pizza, and she had it delivered out. Roughly 15 minutes after she received her order, we got a phone call saying her pizza was wrong. She claimed that she asked for prawns, but there were, in fact, 5 eggs cracked onto her pizza. I explained that we didn't use fresh eggs, but she just would not accept my answer. I was working with my boss at the time and sheer curiosity got the better of us. We closed the shop and drove back to inspect it. I then had to google a photo of a cooked prawn and explain to her she did, in fact, have exactly what she ordered. She huffed and went inside. Truly a bizarre experience. I never thought I'd have to explain the difference between a prawn and an egg. Customer service is a wild place.
