After reading a few jokes, let's find fault.

I work in a bank and manage self-service cash machines. Once a customer called me at two o'clock in the evening and said that the money was swallowed by the machine when saving money. I comforted him with gratitude and promised to deal with it in time the next day. The next day, I turned on the machine and saw an envelope! There is a pile of money in the envelope, tied with rubber bands!
