0This might have been from an old police show. Breath testers used to be much more expensive. Instead of having one in each police station or even portable ones in cars like now, there might have only been one for the full city.

0 In a British tv-show called 01i00Heartbeat 02i00the police officers did use this balloon-like-device if they suspected someone being drunk. The show takes place in 1960s or so in Yorkshire. 0-
