Elder parents....grrrrrrrrrrr

Tonight my 72 yr old father is telling me how he needs a $500 malt machine
to make a good malt. Now keep in mind he has never shown interest in making
a smoothie, milkshake or mexican liquado. I told him that people that buy
malt machines when not needed have more money than brains.

My father is the type of pack rat that has one of everything but only uses
those items once in 10 years.

Don't retirees think of anything else but how to squander their hard earned
money on junk shown on the Home Shopping Network? Especially ones that have
a collection of tools and gadgets that they don't currently use?

Can someone please answer 3 basic questions?

1) What is the big difference in a malt vs milkshake?

2) Does Dad need a malt machine, won't a blender do?

3) Can you share some basic recipes?
