change the standpoint and can get to know the invisible thing.

Today I went to convenience store worked for 3 hours.

and I met one customer who was so angry ageists me.

but I think I also had a bad point, although it is only the  value that can be used only in radical customerism-capitalism society in Japan.

but it is not so bad in another country.

so I am not required to blame myself.

but if I want to live in this society, I'd better to do in accordance with this value.

the point that I should change in working is to think about the viewpoint from customer.

even if the viewpoint from worker is not so bad,change the viewpoint you can get to know a little bit impolite。
