Do you have cold medicine?
Yes, but do you have a prescription with you?
No, I don't.
I'm afraid you can't buy any medicine without a prescription from a doctor.
I have a headache. Is there anything I can buy without a prescription?
Then you can buy Aspirin.
I will take the Aspirin then. And have you a small first-aid kit?
Yes, here this is.
I'll take it too.
Thank you and take care.
