What is the probable relationship between the two speakers?

A: Listen, the heating is broken in my room. When are you going to come and fix it?
B: I’m sorry to hear that, sir. I’ll get someone right away.
A: You’d better. It’s freezing up there. And my room’s a disgrace. That maid is useless. I want her replaced.
B: Well, I’ll speak to the housekeeper about it, sir, but I’m sure
A: And that hall porter’s another one. You should get rid of him, too. He doesn’t know how to treat guests with respect.
B: Well, I’m very sorry, sir, but George has been with us for twenty years and we’ve never had any complaints about him until now.
A: And another thing! What are you going to do about those foreigners in number 27? Carrying on all night in that funny language! Shouting, they were. It shouldn’t be allowed.
B: If you like, sir. I’ll have a word with them and ask them to be a little more considerate.
A: Yes, do that, will you, then maybe I’ll get some sleep.
B: I’m very sorry you’ve been disturbed, sir. But are you enjoying your stay apart from that?
A: Well, I don’t think much of the restaurant. I can’t get a decent plate of fish and chips. It’s all salad and fan cy stuff. And the service is terrible, too.
B: I’m very sorry you feel that way about it, sir. If there is anything else I can do to make your stay more pleasant, please don’t hesitate to ask me.
