I went to a Chinese Buffet by myself once and ran into to a group of people I went to high school with and felt immense shame.
concerts and movies alone GOAT as well
love going to movies alone but don’t think i’d enjoy a concert as much by myself
i eat alone all the time, but not a nice place where you would book a table and have service etc, going to those places to me are about an occasion spent with others
op has to be trolling
would be funny though to book a table for 10 turn up in a tux by yourself at a high end resturant
