Where does the dialogue probably take place?

M: Can I help you?
W: Oh, thank you. Would you mind putting my case on the rack?
M: Not at all. There you are.

M: It was all my fault. I wish I hadn’t been so thoughtless. I used to come back late from work, after stopping off at the pub on the way home, and didn’t lift a finger to help when I did get home. I should’ve helped more with the baby and things like that.
W: Well yes, the main thing if you ask me is that you shouldn’t have taken on that new job in London when she’d just had a baby.
M: Now I’m a divorced idiot.
