On which day of the week are they having the conversation?

W: When are you going to get your hair cut? It’s not long till school starts again. I thought you were going to do it yesterday.
M: Well, I’ll have to go tomorrow or the next day. I couldn’t go yesterday. It was closed.
W: I thought it was always shut on Wednesday afternoons.
M: No, it’s shut all day Tuesday.

W: Er, it’s these curling tongs I bought here last Saturday.
M: What’s the problem, Madam? Is the item not functioning?
W: No, it’s your price-beater guarantee. You clearly said that if I found them at a cheaper price in any other shop, you would refund the difference and well, imagine my surprise when I went into Lunthams and saw them there for only trine ninety-nine. I mean...I know they were on special offer but that’s not the point.
