Am I wrong for being petty?

Long story short, plans changed and my roommate assumes I’m getting a ride to the bar. I get off work at 10pm. The bar is a fifteen minute walk from my job. I’m uncomfortable walking at night but since it’s fifteen minutes, I did it. I asked my roommate to pick me up from work. A four minute drive from the bar. He and two others already left for the bar at 9. My friends are saying he should’ve picked me up because no matter where I am it’s dangerous at night. I’m currently at the bar and no one has noticed I arrived. Like all three of them were at the pool table next to the entrance and one even stood right next to me when asking the bartender something. I haven’t made myself known to them nor have a received at “wya” text. I sorta want to see if they’ll notice me sitting two tables away from them or at all. Am I being petty?
