I 28f have an extra day off work and I'm planning on surprising my coworker 21m. I know his schedule because it rarely changes. I have some shopping i need to get done that day which means I'm gonna be in the area anyway. I'm gonna do something like bring him a coffee or an energy drink. Maybe both at the end of his shift. I got to work with him an extra day which was a very pleasant surprise as I normally only work with him 1 day a week. He goes out of his way to talk to me and stand by me as much as possible. One of the cupholders isn't working properly so the cups will sometimes spring out. My coworker thought it would be funny to mess with it and make them jump. I go to push them back while both of us are laughing our asses off. I said would you stop?! He comes close to me and puts his hand on top of my hand. It was also pouring that day. I made a joke about not needing to shower when I get home cause at this point I'm already gonna get my shower in. He looked down and laughed like that thinking something dirty laugh. My shift was 2 hours longer than his. The next day we have the exact same shift. At the end of both our shifts, I sit at the table across from him. His entire face lit up and we had a nice conversation until his ride came to pick him up. He lights up anytime he sees me. I told him I liked the convo we had and we've been messaging each other back and forth. I might be the asshole because I don't usually go to my workplace on my days off and I don't wanna scare him.
