Here is a dialogue on buying safety materials for Corona Virus from a shopkeeper.
Myself: Excuse me, uncle?
Shopkeeper: Yes, dear? How can I help you?
Myself: I need a box of one time masks, another box of blue non-woven head caps, two packs of handwash and two bottles of hand sanitizer. Do you have all of these?
Shopkeeper: Yes, of course. Please wait for a moment and I will get those.
Myself: Yeah, sure.
Shopkeeper: Here are these.
Myself: Oh, no, I wanted the refill packs. Don't you have Lifebuoy Handwash refill packs? I don't need bottles!
Shopkeeper: Oh, sorry, however, we have that one too. Let me exchange this. Here it is, Lifebuoy Handwash refill packs.
Myself: And I haven't used this sanitizer before. Don't you have Lifebuoy or Detol sanitizer?
Shopkeeper: I'm so sorry. We don't keep those. But you can take this. It's Sepnill Hand Sanitizer. It's made in Bangladesh and it's so good as well as cheap.
Myself: Oh, really?
Shopkeeper: Yeah, you should give it a try.
Myself: Umm, okay. I will buy this. So, how much in total?
Shopkeeper: Let me calculate. It's, umm, yeah, 900 Taka only.
Myself: Here you go.
Shopkeeper: Here is your return. Thank you for coming. Hope to see you soon.
