Am I wrong for being mad my friend brought someone to dinner without asking?
You made a reservation for six and seven people showed up. Are you overreacting, or was bringing an uninvited guest genuinely out of line? Here's the ruling.
The host
They planned a specific dinner for a specific group — a table booked for a headcount, a seating plan, and in some cases food or cost split around that number. An extra person they've never met changes the whole dynamic of the night and they got no say in it.
The friend who brought a guest
It was a casual group dinner, not a formal event, and their partner or friend was already with them that evening. In their circle bringing someone along to a big group thing has never been a problem before, so asking felt like making a formality out of nothing.
The verdict
Who's at fault
The friend who brought a guest is more in the wrong here. The friend is mostly wrong here. The rule is simple: if someone else made the reservation, you ask before adding a person to it — a two-word text solves this and costs nothing. "Nobody ever minded before" isn't permission, it's an assumption, and it puts the host in the position of either being visibly annoyed in front of a stranger or swallowing it all night. That said, the host doesn't get to be silently furious for three hours and call that handling it. If the extra chair was a real problem, the moment to say something was when the text came in, not in a group chat post-mortem the next day.
“"Nobody minded last time" is not an invitation — it's a guess you made with someone else's reservation.”
