If you've worked in customer service, you know that most adults secretly have the taste buds of toddlers. That's not necessarily bad, but when the 20th grown adult of your shift orders their meal with "no veggies," you start to question the general population's ability to consume a genuinely nutritious meal. At a restaurant where I worked, the chefs eventually stopped putting vegetables on every dish because that was the request more often than not.
If you work in a restaurant where people can easily customize their food, you also know that people can get creative with their meals. This creativity might annoy you, but some requests can get so absurd that they are unbelievable. Twitter user @pb_and_garlic experienced such an instance when a customer asked for a sandwich nobody could have possibly dreamed of. The only plausible people who could've requested this sandwich are a horrifying Midwestern monster and this girl.
