Will They Be Serving Drinks?

During the summer, I volunteer at the library a few nights a week. Recently we have been preparing for a grand Harry Potter extravaganza for the elementary school kids. One of our strenuous duties tonight was calling all of the families that signed up and reminding them of the time, date and such. It was a hard task given that we did not know how to answer any of the parents' questions; we were just reading off a script and had no clue about any of the details of the night. During our break, a few of the other staff got together to share funny stories about how our mission went. The funniest call, hands down, went something like this:

"Hello, I'm calling from the library to remind you that you've signed your child up for the Harry Potter night...When you arrive please bring your form you received after you signed up... "
"Wait! What if we don't have a form?"
"Sir, everyone was given a form."
"Well, what if I lost it."
"Uh, maybe you should find it."
...
"Er, Okay. Oh and will they be serving drinks?"
"Excuse me?"
"You know, like beer."
"Um, I'm sorry but this is a children's program. They will not be serving alcoholic drinks at the library."
"Oh okay. Thanks"
