My wife works part time in customer service in restaurant --- one of those professions I could never do.

I am convince that I never forgive an arrogant customer.

-----

Now an order system using a tablet seems to be ordinally in the food and beverage field.

This system has merits that decreasing labor costs and order errors, and less frustration when an order is not picked up for customers.

Of course, it is inconvenience for customers who are not familiar with this tablet system.

-----

Recently, old-agers who cannot use a tablet become social problems.

Of course, we have to support theses old-agers who cannot use a tablet, however, my wife said that some old-agers who got angry when she asked them to use the tablet, are increasing.

Hearing wife's story, it is me who come to angry.

"Our clerks are our most important asset. Any customer who yell at our clerks will be asked to leave. We will "refuse" next your visit.

When asking her, she said "it is impossible".

(Actually, this (banning) is legally possible (Civil Code Article 521 "Freedom of Contract").

-----

This is a interface problem of old-agers not tables.

(1) The old man who yell "You take the order"

(2) The old man who bows his head and says, "I'm sorry to repeat some questions again, but could you please teach me?"

Our society think that we cut out the the above (1) old man, and want to support the above (2) old man.

Now I am systematizing this emotion, and creating "the system that cut arrogant customer off"

-----

I will tell the old-agers who live by the old-fashioned value system of "the customer is God".

I destroy this values.

Eventually, my system will be designed to eliminate those old-agers.

I think that they should change their interface, and tune them into "the Ebata's system".
