The guy who answered the door looked like he had just seen a ghost and was a little jittery so I'm pretty sure he was on some kind of drugs.
Anyways, he hands me $10 for a $15 bill and tries to go back inside really quick. I realize that he didn't hand me enough money so I knock on the door and tell the guy he still owed me like 5 dollars so he starts patting his pockets and finally pulls his hand out as if to give me more money but has nothing in his hand. He extended his hand to give me this imaginary money and was visually surprised when I wasn't fooled by his trickery.
The guy does this 2 or 3 more times before having me call my manager to attempt to use his card to pay even though I'm sure he knew it wouldnt work. At this point he goes back inside because he "just heard his roommate come in" and is going to "borrow money from him". So I wait, and I wait until I knock again. The guy cracks the door, sees its me, and closes the door again really quick like he was surprised I didnt go away. Eventually after about 10 minutes of annoyance and feeling like I might get stabbed I told the guy I either needed money or the food, which he reluctantly gave back. All in all a very strange experience. – billmurraywins
