People with job they shouldn't have (photography shops)

I call a local Photography supplies shop today and some dumb blond i'm sure, I call and asked it they had the Digital sensor cleaning Kit, she reply she didn't know what type of kit i was talking about.

Ok if you work in shop that sell camera and photography equipment and you don't know what a Digital Sensor cleaning kit is then you need to find another job. the owner need to get rid of this person. I can only guess that reason why she is there is to service his needs..

Proving that some people have jobs that they are not qualified for.
