i was taught by an older kid how to make free phone calls on the old button A / button B phone in the club. A trick that became very useful in the UK to make trunk calls home from school. Who was that Kid ?
I did the same thing at the club. 7 clicks, 4 clicks 2 clicks 4 clicks. Little Aden 7424. Occasionally I would lose count of the clicks and dial the wrong number. They must have got wise to this as the phone was replaced .
