Well there's certainly nothing wrong with your long term memory! Dad insisted on having the walls of the shop lined with sparkling glass jars full of sweets. This was maintained by having two jars, one behind the other, so that as soon as sweets were sold from the front jar, when no customers were in the shop , we would have to replenish from the jar behind. The jars also had to be polished at least twice a week.
Dad had a 'war' with Woolworths when they started selling Cadburys misshapes and Cadburys wouldn't supply him with this line. The only way he could get hold of these was to buy in the same quantity as Woolworths. Dad was stubborn and would not be beaten, consequently we had a huge container load of these chocolates to store and then sell! This stock had to be put around the walls of the upstairs stockroom - if the boxes had been put on the floor the ceiling was in danger of collapsing!
You're right, he did sell home brew ingredients at a different site after that. We had a cellar full of the stuff at home and past boyfriends would love their talks with dad over a glass or two. Dad used to call it his truth drug as he would learn all kinds of secrets after a few.
Time does fly, but thankfully the memories stay.
