Arthur: It's really 'orrible here. The food's awful.
Betty: Awful food.
Arthur: And not much of it either.

Betty: No, she only allows you one jacket potato a day.

Del:Well you never know, she might give you an extra lump of custard with yer afters.
Arthur: Well she hasn't previous years.
Betty: No.
Arthur: Aye.
Del: Well, stay lucky.Del ascends the stairs.

I ordered my OFAH box sets from BBC America. They contain many of the scenes which are cut from the British releases according to wikipedia...and Aaron.
But this scene you're describing is not among them.

I had this on VHS about 12 years ago in a special box and I remember this scene being on the tape.

One of the most frustrating aspects of OFAH content - the lack of extras and the many cuts.

The demand is there for the BBC to re-release the full series with all cuts included.
