Not sure what exact age you are again Phil but from memory you have been walking the planet a few more years than myself, I turn 55 in a few days btw, the way I see it is this, High Street Shop Gambling spreads back years, I mind my old Grampa having a bet as horses were in his blood, he was the very last blacksmith / Farrier in the town where I was born, all the local farmers would bring their horses to my Grampa, he bought the racing paper religiously, everywhere he went I still mind him having pockets full of loose polo mints that were all for horses, NOT for me and my Sister lol.
I dare say Cos my Grampa was into horses / gambling it was then only a matter of time before my old man started having a bet, and he did, my old man ended up working in a bookies chalking up the prices in the days as WE both know before the bookies had TV screens.
I personally got into gambling on horses cos as a kid we were allowed a punt each year on the Grand National, my first ever go was on Red Rum, AND I only picked it Cos back then I was just as thick as now in that I struggled reading, the easiest horse I could AND READ in the line up was RED RUM, we know the rest and I picked the bugger both years it won in a row, I guess back then that was the first seeds going down with gambling on horses, I was also following my Grampa and my own Dad.
BUT Just like you WE along with others / family members etc etc etc would only gamble by walking into a betting shop, everyone in the local shop / shops knew each other, who yur Dad was, where you lived blah blah blah.
That generation is now dying off AND NOT BEING Replaced, today's younger generation are either NOT Gambling ''Which is Fk'n Wise'' or IF they are gambling they are doing it Online, same as they do most things ..... ONLINE!
The old guy that smoked his pipe in the pub then walked over to the Bookies for a bet is now gone, ALL the Characters from ''THE OLD DAYS'' are gone.
