Kitchen area has had some work done. 2 tradesmen were in the house working on it for a whole day. Obviously they had breaks in between (went for lunch, etc).
Person A and Person B are married and live together. A was the one at home while the tradies were in, while B was out at work.
A told them they were welcome to make their own drinks (tea, coffee, etc), but wouldn't personally be serving them anything.
B thinks A was rude and had no manners, as making drinks and food for tradies is basic hospitality and costs nothing.
A insists it's not about the cost, but about the principle. A refuses to act as a 'servant' to random men who are simply doing their job (and being paid a lot of money for it).
B still disagrees and thinks A was being disrespectful.
Who is BU?
