AIO being bothered that a contractor asked my wife to make him coffee

TLDR- A contractor working on our house asked my wife to make him some coffee

I came home and went into the bathroom to check the progress of our bathroom remodel. When I opened the door, my favorite coffee cup was sitting on the counter. Confused, I asked, oh, Xxxxx, made you coffee? He said, yeah.

At first, I thought nothing of it because I have a very old school traditional wife. But it kept bothering me so I asked my wife about it.

I said, Did you make xxxxxx coffee? She said yes. She then told me he asked her to make him coffee. I said what? She said, yeah. She said, he said “if it’s not too much trouble could you make me some coffee.”

Why am I bothered? My wife is a housewife and mother to X amount of children. The contractor is also married with a newborn. I feel like him asking her was unprofessional or personally intrusive. It would have been different if my wife had asked him if he wanted some coffee. Am I overreacting?
