I’ve only seen that for people with similar first names as other people in a school or workplace. Then again, I was born just before the Brayden/Ayden/Mxyzptlkayden generation.
I guess I just don’t go to so many restaurants thst need reservations for it to be a big deal, and I think in the past it’s even been occasionally just a phone number. But fair enough.
You know you can give them a fake name. I've known several people who had a go-to name for restaurant reservations or something because their last name was just too complicated or too common. No one's checking ID.
