Would you find it weird?

Hi all! I’m a waitress at a restaurant and today a man left his card so i looked him on FB and just messaged him letting him know his card was there! I told my boyfriend about it and he got really mad and thinks i was trying to hit on him? I really wasn’t, but I’m in my 20s and the guy looked around there so i made use of social media and the fact that i had his name to do something nice but my BF keeps saying it’s weird. I’ve been reached out to because I’m notorious for losing my license and i genuinely appreciate people letting me know!

Ugh i just don’t know if I’m the crazy one sometimes anymore.
