If you’re planning on visiting London this summer, you might just want to familiarise yourself with some British Slang expressions that are very commonly used by the British. They will be very useful particularly if you’re likely to be socialising with Londoners.
"Mind the Gap" was introduced on the Tube in 1969. Currently the message "Please mind the gap between the train and the platform." is piped into the arriving train carriages, but it used to be broadcast over the station PA repetitively, in BBC-style received pronunciation. "Mind the ge-yap!" Much to the delight of visiting tourists. It was actually the sound engineer's voice, as the actor originally cast wanted royalties. Bank station on the Central Line is one place where it can be heard.
