how much do you dislike working with slower partners?

I've worked for starbucks for about a year and a half now. I really love my coworkers and feel like I get along with everyone pretty well. I regularly open and think I do a pretty good job of getting tasks done in the morning. The only thing I'm insecure about is my speed. I figured it was something I'd eventually get better at over time and while I've definitely improved since I first started, I'm just not very quick. Bar, making back-ups, dishes, doing cold-brew, etc. It's not for lack of trying and at this point I just feel embarrassed about it. I should be better but I'm not and it makes me feel stupid. My biggest fear is that I'm a nuisance to my coworkers because I understand it's a fast paced job. I just want to know from a general perspective how annoying this is for others and what advice you might have if any?
