can i go back?

so, yesterday afternoon, i got lunch with a friend at a café... the waiter was very attractive and very flirty with me... i thought he was very cute and had a great personality so i flirted back... anyway, later that day my mom asked me to get dinner with her at the same restaurant and i said yes... coincidentally, we had the same waiter and again, he was very flirty (my mom even commented on it when we left)... he asked me for a high five (and his hand definitely lingered) when we were leaving, which i thought was strange but idk... if the feeling is mutual, i’m totally interested. anyway, would it be weird for me to go back to the café next week because i kind want to see him again? lmao, am i crazy?!
