Find that the advert and the reality were some distance apart.

Two products stand out for me.

1. Tins of Spinach , made famous by Popeye the sailorman. Supposed to make
you superhumanly strong but didn't and tasted like putrid shit.

2. PLJ - stood for Pure Lemon Juice but advertised as a refreshing squash type
product when it was so sharp as to be undrinkable.

The slaps I got as a kid for creating a fuss to be bought these products only
to say " they taste awful " live with me to this day.

Parents beware.
