The difference between a regular cup of coffee and a cafe latte at 7-11 in Japan is 50 yen. And in one recent case at least, a call to the police.

At around 7:30 in the morning on January 21st, a 62-year old man was arrested on suspicion of theft by Fukuoka Prefectural Police at a 7-11 in Nakagawa, Fukuoka, The Sankei News reports. The man purchased a 100 yen cup sold to be used for a serving of regular coffee from the convenience store's beverage server, but filled it instead with cafe latte, which requires a separate cup priced at 150 yen.

The man's attempt to buck the store's system was noticed by the store manager and customers, and police were summoned to the scene. While he initially said that he simply pressed the wrong button, he relented after further questioning and said he did it on purpose. After speaking with customers in the store, police suspect the man is a repeat offender.

Calling the cops on someone trying to cheat a coffee serving system may seem a bit extreme to some, but it's at least not as bizarre as a the man who was arrested for attempted robbery after politely asking a convenience store to let him do so.
