20 dollar bills you get out of a Mac machine. The newer ones that stick together as if they were glued.
Also always check your money before you leave. I drew money out of one of my accounts at a local Sheetz convenience store. When I took it out of the machine the stack of bills seemed a lot thicker than I expected. I started to count it and it didn’t take long to realize I had more than I wanted to withdraw. Before I even got done counting it a fellow about 15 feet of the left of me asked if I had any trouble using the machine. He said he wanted to withdraw $400 but ended up with nothing. I said let’s go see the manager. I handed her the stack of bills, explained what happened and asked her to count it. Sure enough not only did I get the amount I wanted, but also his 400. The receipt I got out of machine only showed the correct amount that came out of my account. All’s well that ends well I guess.
