No Subs

Barb likes to get the non-generic drugs when we get a prescription although she can never remember whether the real brand is called the generic brand or the non-generic brand.  However, for our insurance to pay for the non-generic drugs, we need to get the doctor to write "No Subs" on the prescription each time.  I forgot to get the Dr to write "No Subs" on my prescription and Barb thought it would be a hassle to take the prescription back to the doctor just to get him to write No Subs on it but she did it anyway.  She brought in the prescription and told the receptionist what she wanted the doctor to do and the receptionist just grabbed the prescription and wrote No Subs on it herself.  Barb wondered what was stopping us from writing No Subs on it ourselves. She probably didn't even have to get the doctor to do it.
