This morning...

Post by Kevin Johnson » Sun May 19, 2019 11:36 am

After Samantha and I ate breakfast we went to the local food store (which shall remain nameless but it is a large chain). Samantha had been given a rain check for electrolyte drinks.* The packs are regularly $9.00 each but the rain check is for a buy one get one free offer (BOGO).

She picked up eight packs and went to the cashier who took the coupon and promptly charged her card for $72.00 and tax.

Now she had to get a refund from customer service.

Customer service said that they understood the problem and promptly entered eight packs at regular price and eight more packs at $0.00, so sixteen packs in total. Samantha pointed out that, first, customers are limited to eight packs total and, second, that this did not address that she wanted to only pay for four.

The customer service rep brightened ... "Oh, so the packs are $9.00 each so half of that is $4.00."

If the register does not calculate it for them they are simply lost.

Sigh.

* Aside: drinking these electrolyte drinks has stopped the severe muscle cramping in her legs. It has been yet another saga in trying to make some local doctors believe that.

I find when you can do seemingly simple head math as fast as the other person is talking, the blank look you get back is not them in astounded admiration that you are calculating as fast as they are talking,,they just work out that as you are old you must be just babbling again.

I find if you tell someone in this situation that you are not comfortable and reluctant to get into an intellectual battle with the ill equipped, their smugness is prolonged, this,realization if it sinks in will be after you leave or not at all.

Cheers.

The Father of the exchange family that I stayed with in Germany had (has -- he is still with us) close to or actual eidetic memory for numbers and figures. He was interviewed by the town paper (he turns 90 this year, I believe) and he stated that he remembers all the work he has ever done with numbers.

I played chess with him as a teenager and when he had won he went through all the moves in the game to show me the tactical error(s). :lol:

When my Grandfather was growing up in England (1920s) Maths class involved doing mental arithmetic which he was good at. Samantha just said that her Mother had to do this in Germany as well and the teacher would rap them with a ruler if they got it wrong.

Edit -- they got wacked if they used their fingers! :lol:

I now have sets of micrometers I could never have cost-justified when they were new. Today’s machinists don’t or can’t read vernier; gotta have direct reading digital. Thus the old vernier metrology is going for cheap.

Ah yes,,the vernier scale, great if you have good eyesight,I still have a vernier height gauge at the back of the face plate just for old times sake. Just looked at it then and can still read out a measurement but i would have to say i would not switch back from the digital measuring instruments that are everywhere here. I have also kept my school slide rule from the 60's, i have pulled that out in nostalgic moments and can still get a sum.

Cheers.

Local Greek restaurant owner knew about that device by heart. They are deservedly very proud of it.
