I have a client for more than 10 years. Why do I keep writing down my data every time?

It is about getting better...

I just finished my blood exam in a diagnostic center.  I know that they use computers, may be for a show or for typing jobs.   

I have been patronizing this medical facility for the last 10 years.  But every time I go there I have to write down everything about me again and again.  

Its unlike the procedure at an MVP hospital where you register only once.

Why have they not improved?
