What is Cathy fed up with? ______ on packing cases

Cathy: I’m fed up with sitting on packing cases, Joe. Don’t you think we could buy at least two chairs?
Joe: Do you know how much a new chair cost? One cheap comfortable armchair... eighty pounds.
Cathy: Yes, I know. It’s terrible. But I have an idea. Why don’t we look for chairs at a street market? I’ve always wanted to see one.
Joe: All right. Which one shall we go to?
Cathy: Portobello Road, I think. There are a lot of second-hand things there. But we’ll have to go tomorrow. It’s only open on Saturdays.
Joe: What time do you want to go? Net too early I hope.
Cathy: The guide-book says the market is open from nine to six. It’s a very popular market, so we’d better be there when it opens.
Joe: Right. I’ll set the alarm.
Cathy: Oh, Joe. Look at the crowd.
Joe: They must have the same guide-book that we have.
Cathy: But it’s very exciting ... look at that old table-cloth and those beautiful curtains.
Joe: Aren’t we looking for chairs?
Cathy: Yes, but we need curtains. Come on.
Cathy: Whew. I’m so tired that I can’t even remember what we’ve bought.
Joe: I can. A lot of rubbish. I’ll make some tea. You can have a look at our "bargains".
Cathy: Joe, the curtains are beautiful but they’re very dirty.
Joe: What did you say?
Cathy: I said the curtains were very dirty.
Joe: Why don’t you wash them?
Cathy: I can’t. They’re too big. I’ll have them dry-cleaned.
Joe: And what are you going to do about those holes. Can you mend them?
Cathy: I can’t. I can’t sew. I’ll have them mended.
Joe: How much will all that cost? I never want to see another bargain... and we still haven’t got any chairs.
