Oblivious to flirting

I was buying a new phone from a store as my old one went through the washing machine. The guy serving me literally asked me “So what are you doing later tonight?” It didn’t even register in my brain that he was flirting or trying to ask me out. And I just nonchalantly replied “Oh after work I’m getting groceries then heading to yoga”. He was like “Oh... cool”. Then I strolled out with my new phone. Got back to my car and realised... huh... maybe he was trying to ask me out?🤔🤦‍♀️

Is anyone else as oblivious as me?
