A dialogue between chemist and customer at the pharmacy

Chemist: Hi there! How can I help you today?
Customer: I need to buy some medicines.
Chemist: Sure thing! Which medicines are you looking for?
Customer: I have a doctor's note for medicines for my wife.
Chemist: Could you show it to me?
Customer: Let me find it in my coat pocket... Ah, here it is.
Chemist: The prescription lists five medicines. Unfortunately, we're out of the last one. But you can have the first four if you'd like.
Customer: When can I get the missing medicine?
Chemist: You can pick it up on Friday. We've ordered it from the makers and expect it to arrive by then.
Customer: Okay, please give me the available medicines for a two-week supply.
Chemist: Just a moment, let me get those for you.
Customer: Thanks!
Chemist: Is there anything else you need?
Customer: Yes, now I'm looking for some common medicines for my family. Do you have Anacin?
Chemist: Yes, we do. How many tablets would you like?
Customer: I'll take a packet of ten tablets, please.
Chemist: Here you go.
Customer: Also, I need a tin of first aid dressings and some good cough syrup.
Chemist: I'll have those ready in about five minutes.
Customer: Oh, and do you have good toothbrushes and small toothpaste?

Customer: I also require a small bottle of Dettol and a tube of Burnol.
Chemist: Here you go.
