After some time I saw my doctor and he prescribed me a receipt, but he had prescribed me this receipt in the name of his mother Mrs. Ingrid, by mistake.
I didn´t notice it, took this receipt, went to the drug-store, gave the receipt to the pharmacist together with the insurance card with the name John on it.
The pharmacist took a look at me and has told me:
"Dear, Mrs. Ingrid the name on the receipt doesn´t correspond with the name on the insurance card."
