Years ago I used to make a regular visit to the mag section of WH Smiths on a Saturday morning.
The place used to be swamped by people browsing magazines so getting straight to your mag of choice could be a problem.
I soon learned that a carefully released fart could open up a wide gap in the crowd to allow more efficient browsing..
Just another top tip from L20
Can also be used at car boot sales etc etc etc etc..
Anyhow I got a high score ( at last )
