^^ As did I :-)
However, they are micro and not Standard, actually nothing has been standard for more than 10 years, they were the credit card sized ones, then comes the mini which most people are familiar with, then the micro and lastly the nano which current iphones take and is actually smaller than the chip printed on it! https://www.doro.co.uk/doro-6520.html
bhg, that probably is the most common but technically it's a mini SIM so if Norm asks for a standard SIM he'd get the wrong size, best just to tell the shop what phone it is for and let them sort it :-)
I stand corrected Fitzer - the last phone I had with the "Standard" SIM (using your terminology) was more than 10 years ago and I assumed they were now extinct.
