Why is banking becoming a problem for me?

To the editor:
I have a problem that no one in this town seems to know why?
I do not carry a large amount of money on me. I carry checks. Both Kentucky Bank checks and checks I order supporting ASPCA to help advertise for neglected and mistreatment of animals.
Both type of checks have routering number and bank account number, name, driver license, address and telephone number.
There are two stores that will not take my checks.
I have lived here in Cynthiana for over 50 years. As the widow of Charlie North who was a commissioner.
The bank cannot explain it. One (the manager said come and shop in the morning I can put your check through. If she can, why doesn’t she teach her employees how to put a check through the register?
