Women, do men ask you, "who did you go with or who took you?" when you show them, you did something fun by yourself? Men, why do you do it?

When I had to go to an appointment, a guy asked who took me. When I showed off what I ate at a restaurant , another guy asked "who bought it for me?" I've chalked up male strangers asking me, "where's my boyfriend or husband at?", as flirting, but some of these men were so serious about pushing me into a relationship with a man, any man.
Yesterday I went to a festival by myself, had no friends, and still had a good time. Again, I got asked who did I go with. Is this common behavior for men?
How many times have guys done this to you?
