用英语「在药店买药」
Hi there! Welcome to our pharmacy. Is there something specific I can help you find today?
Yes, I'm looking for something for a sore throat and a mild cough. I've had it for about two days.
Of course — two days is pretty fresh, so you have some good options. Do you have any other symptoms alongside the sore throat, like a runny nose or fever, or is it mainly just the throat and cough?
