Palmer: May I help you?
Karrie: Yes, I want to buy some shoes to replace the ones I am wearing.
Palmer: What's wrong with them?
Karrie: They are too old and shabby.
Palmer: I can see they are simply worn out. Would you like the same color?
Karrie: Yes.
Palmer: How about this light brown pair?
Karrie: Yes, I'll try them on.
Palmer: They certainly look charming.
Karrie: The trouble is they feel uncomfortable.
Palmer: Then try on another pair of the similar style.
Karrie: They are much better. Do you have them in red'?
Palmer: Yes. Would you like both pairs?
Karrie: Yes, if they don't cost too much.
Palmer: Oh, no. they don't. The second pair is half price. Shall I put them both in the box for you?
Karrie: Just the red and the old ones. I'll wear the new brown pair home.
Karrie buys two pairs of shoes in a similar style to Karrie's old shoes with Palmer's assistance.
