What is the largest tip you've ever seen? One waitress, going by the name of Sara received a super fat tip from a party of three people - two women and one man. Too bad it turned out to be bogus.

One of the women reportedly told her: "I will be your guardian angel today. You've never seen a person like me. You've never had a table like me. This will change your life." Sara saw the woman had written a $200,000 tip.

However, Sara was disappointed to find that the bank rejected the exorbitant amount.

Here's a copy of the receipt, which the waitress posted to Reddit. Talk about being really rude:
