My parents owned a business so my brother and I would watch the shop on our own while my parents were taking a break or out buying supplies. We’d goof around a lot and there was this one time he let out a gigantic fart without realizing there was a customer in the store.

Also, when I was working in a cafe in Japan, my coworker answered the phone and instead of saying ohayōgozaimasu (good morning), she said omedetōgozainasu (congratulations).
