You walked in and got your exact ticket number as it was called? Never seen that before. Being handed the wrong ticket waiting 6 hours and being told it is the wrong counter I've had that one. Seeing a woman, paying the money and getting a receipt, than coming back a week later to be told she has never seen me before and ignoring the receipt then asking for me to pay again I have had that one. Being told to stand up again and then told to sit when told and place the document into the officers hands gently I have had that one. Having my passport thrown at me had that as well. Having a bucket of water and feces thrown over my legs by the maid at Laos immigration I've had that one.
